I know this thread is dead, but I seriously feel like, in "theory-mon" (intended), it can:
1.Not even think about the mountains of exp. points from knocking out so many yveltals.
2.Not be destroyed by volcanion's raw power due to lab spamming with hand stun (Ace trainer )
3.Ace trainer greninja (therefore having one of the best greninja MU that doesn't involve using garb), while OHKOing breaks.
4.Reg/glac/garb/ham isn't much of a threat although the hammers can be dangerous.
5.Mmewtwo with garb hurts but is fine if you can quietly setup a mew and lysandre up that garb or play a simple game (raikou->raikou->raikou, etc.) followed by a shaymin KO to clean up. Just don't ever drop a lab unless induced brick is your only remaining win condition.
6.Mray, do we even need to talk about this?
7.vespiquen variants are also pretty ez, (not just with lab -> ace trainer stun ), but because they struggle to dent raikou early game and have no way to catch up.
8.Mgardevoir, lab->lab->lab->lab, (I think you get it) (ace trainer )
9.Darktina, again, hammers hurt but I'm not really feeling threatened.
10.Plumebox and mirror (running jolteon EX) I find the idea of a 1-1 zebstrika more promising than trying to play jolteon into jolteon... (and for any1 who doesn't remember the generally irrelevant ability)
