First you resolve the effect of Alakazam's Poke-Power. THis makes their power not work and you discard two cards. Then, T-Tar gets his Poke-Body to work because canceling a power does not mean it didn't happen. This is why if a player had two Gardevoir SW in play, only one of them could use its power regardless of it if the first one has its power get cancelled or not.~Mark
