You can’t have more than 1 Pokémon Star in your deck.
During your opponent’s next turn, any damage done to Registeel Star by attacks is reduced by 10 (after applying Weakness and Resistance).
Put 3 damage counters on your opponent’s Pokémon in any way you like. If your opponent has only 1 Prize card left and Registeel Star is the only Pokémon you have in play, put 6 damage counters instead.
