Wow I ended up typing up quite a bit, but this was a great battle. Next time I'll try to be more concise.
This is actually a very interesting battle between two good players, with
Life Orb Analytic Starmie being the literal Star of the show.
Yeimi has a bulky sand stall team, with Specially defensive Tentacruel, Chansey, Sableye, Physically defensive Skarmory, and physically defensive Hippodon. It's pretty weird to see Chansey in Sand(in fact, the only pokemon to not be damaged by Sand is Skarmory), but it looks like Tentacruel will have a tough time spinning against IE's team. The team's main source of damage seems to be hazards, with Sableye as the spinblocker. I know that it's a curiously lopsided stall team meant to handle the more dangerous physical threats of OU while Chansey puts the team on her back on the special side of things.
Internet Extension has an offensive team, with CBnite, Analytic LO Starmie, Lead Mamo with Icicle Spear, Healing Wish nonscarf jirachi with Iron Head and U-turn, Bulky Flying gem SD scizor, and a mystery Salamence (likely scarfmoxie). This team seems to function with Jirachi and Starmie supporting the team by racking up damage on opposing threats, keeping the field clear of hazards, and bringing a weakened pokemon back to full health for another chance to sweep, while the physical attackers weaken the opposing team's physical wall to the point where the remaining physical sweeper blows past the opponent's weakened team.
It looks like Yeimi is packing all the answers to IE's physical team with her two physical walls
and Sableye, but also has Chansey and Scarf Rotom-W to handle Starmie, IE's main shot at breaking through Yeimi's bulky team. Scarf Rotom-W and Prankster Sableye are the Yeimi's fastest pokemon, which is important, as everything else on Internet Extension's team will almost always move first. Of course, I didn't know the exact sets the first time I watched the battle, but both players knew what they had on their own teams before going into battle so I'm going to try to speak from the knowledge they had without necessarily spoiling anything. Another thing to note is that Yeimi is playing with the Stall team's mindset, preserving important walls to continue walling the opposing team into oblivion is of paramount importance, therefore she must play while looking long term into the match, with lots of Sandstorm damage, hazards damage, and weakened walls. IE is much more flexible in making risky plays and predictions as losing a Hippowdon on turn three would prove devastating to Yeimi's stall team, as Skarmory and Sableye alone cannot handle Mamoswine, Scizor, Dragonite, and Salamence. With a matchup like this, there is a lot of pressure on both players, and the match comes down to mental toughness.
Turn 1
I found it interesting that IE would lead Starmie on turn 1, given the threat of of Rotom-W leading and threatening to snatch momentum with Volt Switch, and the fact that without Starmie, IE will have a very tough time winning, so why chance it so early? The MASSIVE 25% on Chansey makes it Analytic without a doubt, and more threatening for Yeimi, as only Chansey can switch in on an analytic boosted attack.
lots of kerfluffing around Mamoswine's Icicle Spear and physically defensive Hippowdon slowly Earthquaking it's way to victory, with a depressing string of 2-hit icicle spears followed by a few 5-hit icicle spears until finally, IE switches the weakened Mamoswine out.
Turn 16 - 100% Scizor vs 35% Rotom-W
Internet Extension loses 50% on his apparently non-scarfed Jirachi(who arguably wasn't going to be too useful this match) for no reason due to Hydro Pump to go to Scizor who doesn't even resist water and could be seriously injured by another Hydro pump. Maybe it's Sdef Scizor, but IE chooses for some reason to click Superpower. Yeimi is definitely not staying in on Scizor with her weakened scarfer while Starmie is alive, and Superpower isn't going to touch tentacruel, hippo, sableye, or skarm (chansey is never going to switch in on scizor to begin with) so this move didn't make much sense.
Hippowdon comes in to sponge the piss weak Superpower, taking 21%, and Yeimi now has the knowledge that Scizor is not banded, in fact, Yeimi has the knowledge that Scizor is not even running 252+Atk, therefore that Scizor is of the SD variant(Either 40+ bulky SD or 252jolly SD). Or lolscarfed...
Superpower was a horrible move to use, so why bother sending it out on scarf hydro pump? This isn't particularly a bad move, as IE might have wanted to preserve other pokemon, but weird/pointless because it gave a lot of information and accomplished nothing really.
Turn 20 - Hippowdon at 73%+ vs 44% Jirachi
IE decides to stay in and keep going for flinchhax against a healthy Hippowdon (maybe IE doesn't mind foddering jirachi? Maths dictates that the sand Hippo will win), who Yeimi doesn't bother switching out until its only at 16%. At which point, the sand hippo is finished, because after SR-heck even before SR, everything on internet extension's team can outspeed and KO it, so it's never getting a wish (unless Yeimi is a prediction goddes and Hippowdon comes in on an electric move), and it's too slow to Slack Off. Hippowdon hardwalls Dragonite and likely Mence, so it would have been much better to switch out at least at a more useful percentage instead of preserving Hippowdon for death fodder. Jirachi isn't even that great a threat to Yeimi's team to warrant staying in to potentially EQ it. IE gets very lucky to flinch Hippowdon so many times and not lose his Jirachi. This definitely was a case of annoying "hax," but this is something Jirachi brings to every match when it packs Iron Head.
Turn 27 - 44% Starmie vs 20% Skarmory
Both players made very good moves in the previous turns. Yeimi Brave Birded, hoping to nail Starmie but also denting Dragonite in the process. Scizor and Salamence would take hefty damage and would be unable to do anything in return (unless of course salamence had Fire Blast, which we don't know) while skarmory roosted in their faces. Even Jirachi would be 2HKOed after SR, so it was a good move regardless. IE kind of threw away dragonite, but got to damage skarmory heavily in the process.
Skarmory might actually tank a physical move and roost upon switching back in (only if Tentacruel spins away SR. at 8%, forget tanking anything), so it doesn't make too much sense to switch it out now, unless looking very long term. Skarmory likely has Spikes and can get to work on IE's team once a layer goes down, but deciding not to fodder Skarmory is an interesting move. This Starmie is the offensive LO variant; therefore, it is very likely to have Thunderbolt, and even has Analytic, so every switchin not named Chansey is going to get cockslapped. (Starmie is Hippowdon's pimp daddy in any case) Hydropump has shaky accuracy, and almost definitely IE wouldn't finish off a weakened Skarmory with an 80% accurate move.
If switching in Tentacruel: Best case scenario: Ice beam (to be followed by Psyshock, no spins still) Worst case: Thunderbolt/death.
If IE has thunderbolt, he's using it 100% to finish off the metal bird, because it severely damages every switchin with Analytic, except for Chansey. Hippowdon can come in, heal back SR damage, and promptly be KOed while racking up LO damage on starmie. Chansey is the best switchin if Yeimi didn't want skarmory to go down. Foddering Hippowdon is a close second as Starmie would be down to around 28%, good for two more turns or one after SR damage if switching out.
Sableye is too important with prankster WoW, and starmie eats it for breakfast with analytic ANYTHING followed by hydro pump.
Turn 28 - 28% Starmie vs 28% Tentacruel (PAR)
Both pokemon having 28% on turn 28 is a sign from Arceus that the results of this turn will have major ramifications on the battle.
Yeimi brings in Tentacruel, arguably a worse switch than Sableye, who gets electrocuted and paralyzed for good measure by the hax gods, who are disappointed with this misplay.
Both players, literally shocked by the fact that Starmie keeps his Analytic pimp hand strong decide to make yet another misplay. Internet Extension's balls increase to the size of Jupiter as he decides to Spin the rocks away, take another round of LO damage and Sandstorm damage, and leave his poor Starmie vulnerable to any stray scalds, ice beams, giga drains, or gastro acids the specially defensive Tentacruel might unleash, while Yeimi, still scarred by the beating her Tentacruel took mercifully swaps it out for everyone's favorite Pink Blob. 28% Tentacruel at 25% speed is going to be outsped and KOed by everything on IE's team (after rocks) and isn't receiving any wishes for sure, so there's no reason to switch it out seriously none. You don't run away from a 12% Starmie that could KO your entire team... right? Well with LO recoil and SS, Starmie isn't sweeping anytime soon.
At this point, Yeimi decides to give IE yet another free turn and switches out to Chansey(finally) who can take anything starmie throws at it, Wish, and switch out from whatever physical attacker comes in. Starmie spins away SR at no cost from Yeimi, but pays for it with LO recoil and another turn of SS damage. I'm honestly not sure why this chansey doesn't have protect, and if it doesn't have protect, why it isn't using softboiled as it is being worn down by starmie/SS/SR and getting pimp slapped every two turns. Yeimi uses Wish to heal something, preferably tentacruel, who can actually live an iron head from jirachi, but passes it to skarmory instead.
Turn 31 The Turn which gave IE a solid Win Condition
This turn was huge, because the useless Jirachi is able to bring Starmie back to full health. At this point, it looks deceptively like Yeimi is in the lead with six pokemon vs IE's three, but Tentacruel, Chansey, and Hippowdon are basically dead after SR and any attack, and Starmie can easily handle Sableye, who threatens to neuter Salamence (if its a pure physical attacker and literally if Mence is Male) and Scizor. Two Will o Wisps will be hard to pull off, but Scarf Rotom helps simplify things greatly.
Turn 32 The Turn that Decided the Battle - 100% LO Anal Starmie vs 100% Sturdy Skarmory
Starmie can bring skarmory down to its sash. Stealth Rocks guarantees that even if it switches out, it can be OHKOed by Starmie upon its return. Had Tentacruel spun on turn 28, Skarmory would have Sturdy in all cases, but alas, it hadn't spun. Had Tentacruel Scalded Starmie, we'd have no Starmie and likely, no Skarmory either. Had Tentacruel put down a later of Toxic Spikes, Starmie would still be unable to sweep Yeimi's team. Had Hippowdon not been haxed by Jirachi, he could have KOed the annoying twerp, and that would have been the end of Starmie. But none of this matters. All the damage rolls, low and high, ice shards in pairs or groups of five, good plays bad plays null plays and non plays, contributed equally to the scenario before both players.
Chansey is at 30%ish health and can take any starmie attack, but not two. SS + SR + Analytic LO boosted attack spell doom for chansey, as it will be 2hkoed by a subsequent attack. Full health starmie took the entire match to wear down, and none of Yeimi's pokemon have the health to sustain analytic Tbolt followed by a second cleanup move. Chansey is one of the only answers Yeimi has to Starmie and must be brought in fresh after something has been foddered. Chansey cannot take any physical moves from Mence or Scizor, therefore it can only come in after something is sacrificed.
However, both players fail to notice something very important this turn.
Starmie is Internet Extension's wincondition, as scizor and mence cannot handle taunt/WoW sableye.
Starmie very likely does not carry recover as turn 29/30 arguably was one of its best opportunities to recover, Recover on LO analytic variants is very unlikely, and Jirachi was sacrificed to bring it health (even if it does, rotom-w can easily force it out/KO it later).
Therefore, wearing down Starmie with LO and SS is of paramount importance for Yeimi. Skarmory has Sturdy, and 180 BP Brave bird (STAB factored in) against a very frail Starmie that is strapped for health. Brave Bird was Skarmory's best option against Starmie. This damage output matches the damage on Dragonite earlier.
0 Atk Skarmory Brave Bird vs. 0 HP / 0 Def Starmie: 123-145 (47.12 - 55.55%) -- guaranteed 2HKO after weather
51% damage on Starmie is huge, as it is taking 16% damage each turn from LO and SS. On this turn, should Starmie attack, brave bird would deal 51%+10% LO damage+6% due to SS, leaving Starmie at a measly 32%, enough for just two more attacks for the rest of the match. Even worse for Internet Extension, Yeimi has two potential death fodder pokemon in Hippowdon and Tentacruel, one of which is immune to Thunderbolt, and very helpful when it comes to Mind games with Sandstorm damage.
If Starmie stayed in, Yeimi could clean up/play around LO and SS and potentially win the game. If Starmie switched out, Yeimi would have a Skarmory no longer at full health, and a Starmie ready to come in and OHKO it.
Both players make a huge mistake. IE doesn't preserve his wincon yet again, and Yeimi doesn't transition from the stall mindset of preserving pokemon to take charge of the game and heavily damage the one pokemon that threatens her entire team, choosing to ineffectually bring chansey back in and take a boosted analytic hit, SR and SS, leaving it in hydro pump range.
Yeimi instead chooses to destroy Skarmory's sturdy, and her chances of winning the battle. Chansey is paralyzed, a sign of displeasure from the Hax Gods.
Turn 33 - 85% Starmie vs 12% Chansey
Hydro Pump misses, and Yeimi is seemingly given yet another chance to stay in this match. A standard Chansey should be able to heal itself not just sit around while waiting for it's Wish to come true. Wish but no Protect? If no Protect, why doesn't Chansey have Softboiled? Is it running Counter or Mirror Coat? Seismic Toss? Toxic? Aromatherapy? Whatever set its running, it isn't able to protect itself, and sadly any recipient of Chansey's Wish is KOed by Analytic LO Hydro Pump.
Around turn 40 Yeimi still has a slim (a fairly decent, maybe 35%) shot at winning, but isn't using the standard 252HP 252Sdef Calm nature on Sableye to tank special hits, (He can burn physical attackers) and Sableye is surprisingly KOed.
252 SpA Life Orb Starmie Hydro Pump vs. 252 HP / 252+ SpD Sableye: 200-238 (65.78 - 78.28%) -- guaranteed 2HKO after Stealth Rock and weather
This was a very interesting battle, and both players played well. I'm not going to comment on hax, but it honestly could have gone either way. Very good game.
