New pokemon. Lets go.
Your wall had toxic, and i was actually 2 pokemon up.
I have 2 levitate pokemon on my team.
And my metagross is Impish, EV'd 252 Atk. 252 Def.
Your metagross was probobly adamant, choice scarfed, evd 252 atk, 252 spe.
Metagross was able to survive a fire punch crit from jirachi, so at 200 HP, impish, evd 252 def, with 31 IV's in everything, Meta would survive EQ (damage calcs) and hit you with EQ of his own.
Well that aside lets have another battle if you really are telling the truth. New pokemon.
