As often as you like during your turn (before your attack), move a Technical Machine card attached to 1 of your Pokémon to another of your Pokémon. This power can't be used if Porygon-Z is affected by a Special Condition.
Search your deck for a Pokémon LV.X that levels up from 1 of your Pokémon and put it onto that Pokémon. (This counts as leveling up that Pokémon.) Shuffle your deck afterward.
Does 40 damage plus 20 more damage for each Technical Machine card attached to Porygon-Z.
