The Lv. 1 Smeargle lead needs to be added to this. It has clear wins against so many leads, and can cause problems for almost all of the most common leads. It turns Deoxys lead matchups into a prediction war, which is always fun.
The set is
Smeargle@Focus Sash
- Spore
- Trick Room
- Endeavour
- Dragon Rage
At Lv. 1 with the EVs not mattering.
Against Deoxys (Speed and Attack) it can go many different ways.
If they attack and you Spore, the break your sash at the cost of you sleeping their lead and getting Trick Room up on the switch. Unless they bring in a priority user or a ghost, you can Endeavour it to 1 HP.
If they attack and you Endeavour they go down to 1 HP and they have the choice between KOing your lead and being easy to revenge so not getting SR or any Spikes down or getting SR down as you KO them with Dragon Rage.
If they Taunt while you Spore, they can either KO you as you bring them to 1 HP, break your sash and get up one layer, or set up two layers and leave you with your sash.
If they Taunt as you Endevour they either break your sash and die or set up one layer and die. Switching is an option for them, but they still failed to get anything up.
Darkrai will almost always beat this lead. The only way you win is if they Dark Pulse for some reason or Dark Void misses.
Non-Lum Groudon is perfect, even Lum is beatable. You Spore straight off and they either SR or break your sash. If they had Lum and used SR, you're free to Spore again. Once they are asleep set up TR and have fun with Endeavour. The only way you lose is if they have Lum and use EQ twice, however you do have the option of Endeavouring turn 1 which would bring them to 1 HP. Watch out for leftovers recovery taking them out of Dragon Rage range after a few turns.
Shaymin-S is annoying, if it flinches you lose and lose one Pokemon. If it does not flinch, you sleep it and get up TR and can bring any non ghost switch in to one HP. Fairly even since you do more damage, but they have a getter chance.
Kyogre Endeavour beats Lum variants, Spore beats all others. I've not encountered many with Lum, so it has been ideal setup fodder.
Dialga: See Groudon.
Lum Mew can beat you, but you can still bring it to 1 HP and KO if it uses Taunt/SR first turn.
The best setup fodder has been Lead Giratina-O, and Forry, but from the list of other leads the following can be spored and set up on:Mamoswine, Metagross, Lucario, Infernape, Tyranitar (if it attacks, you die and it is asleep. If it SRs, you sleep it and set up), Cloyster, Qwilfish, Froslass. Actually, that's all of them, lol.
