Once during your opponent's turn, when your opponent's Pokémon uses any Poké-Power, you may discard 2 cards from your hand and prevent all effects of that Poké-Power. (This counts as that Pokémon using its Poké-Power.) This power can't be used if Alakazam is affected by a Special Condition.

During your opponent's next turn, any damage done to Alakazam by attacks from your opponent's Stage 2 Evolved Pokémon is reduced by 30 (after applying Weakness and Resistance).
