So, after *checks notes* nearly three weeks since the last post, I have experimented with two of the original regi trio, registeel and regirock (
Morkal tested out regice so I don't think it is necessary for me to test it). Admittedly, I have tested registeel way more than regirock, but I still feel confident with my findings on regirock (I spent 2-3 full hours just testing regirock, which accounted for about 30-40 games, which I think is sufficient data to find out its niche). But, still, lets talk about the ÜN-ÜN-ÜN mons.
Registeel
Registeel @ Leftovers
Ability: Light Metal
Tera Type: Fighting
EVs: 252 HP / 4 Def / 252 SpD
Calm Nature
IVs: 0 Atk
- Iron Defense
- Amnesia
- Body Press
- Rest
I played for about a week with a registeel stall team (Impressive by my standards, I switch teams like every 3 days), and I have to say this thing is bonkers. Honestly, despite using it exclusively on stall and pp stall (In which it is I believe one of the three essential mons alongside dd kyurem and Deo-S), I believe this registeel set could find its way onto any team. Now, it cannot hit ghost types at all, which is troublesome, but if you can remove them and position it against any mon that can't hit it hard, then it will proceed to boost up and destroy a team. Even quad resists can't take it on.
+6 4 Def Tera Fighting Registeel Body Press vs. 252 HP / 16 Def Slowking-Galar: 144-170 (36.5 - 43.1%) -- guaranteed 3HKO
+6 4 Def Tera Fighting Registeel Body Press vs. 252 HP / 204+ Def Hatterene: 95-112 (29.8 - 35.2%) -- guaranteed 4HKO after Leftovers recovery
+6 4 Def Tera Fighting Registeel Body Press vs. 244 HP / 248+ Def Gliscor: 152-179 (43.1 - 50.8%) -- guaranteed 3HKO after Poison Heal
Even two quad resists and one bulky resist with insane recovery can't deal with it. Rest allows it to threaten the opposing team constantly and the two turns that you can't act are actually great as it allows you to pp stall some mons much easier, as they waste two more pp than you per rest cycle, resulting most times in you winning. Even corviknight with pressure has to be careful with its pp due to this. Just boost up both defense stats after taking out the ghost types, and watch the opposing team flounder helplessly. More defense ev's could be used, but I prefer the increased special bulk. Light metal is also used to reduce low kick from weavile's power, which is a guarenteed 2hit ko otherwise.
Regirock
Regirock @ Leftovers
Ability: Sturdy
Tera Type: Grass
EVs: 252 HP / 144 Def / 112 SpD
Bold Nature
- Body Press
- Rock Blast
- Stealth Rock
- Ice Punch
Regirock is a mon that can take a lot of hits using its massive bulk. With body press, it can also deal back impressive damage as well. Rock blast can help against a lot of opposing OU mons, or ribombee leads by breaking sashes and ko'ing it if you get three hits. It also can help with regirock's uninvested attack stat feeling a lot less powerful (it has 100 attack) than it should do if it gets a 5 hit. Stealth rock means regirock can always make some progress in a match even if it might be facing very powerful special attackers. The last moveslot is customizable, I chose ice punch to deal with dragon types and make grass types wary to switch in. I could see you using earthquake to deal with ghold or even explosion to go out with a bang (pun intended) and deal massive damage to potential switch in. Iron defense could be used to set up a sweep, and is most likely the best option, but I wanted to try something unique.
Tera grass allows it to take on ground types easily and makes it a temporary stop to water/raging bolt sweeps. The ev's are specific, with 112 special defense ev's, you can take two specs kyurem freeze drys, which is nice and allows it to temporarily check it. Overall, regirock is a mon that feels really powerful as a defensive behemoth, and if it just had recovery it would easily be a top tier defensive mon (I love palossand, but gf please give shore up to other ground/rock types cowards).
