Leafeon-GX

Ability: Breath of the Leaves

If this Pokémon is your Active Pokémon, once during your turn (before your attack), you may heal 50 damage from 1 of your Pokémon that has any Energy attached to it.

For each of your Benched Basic Pokémon, search your deck for a card that evolves from that Pokémon and put it onto that Pokémon to evolve it. Then, shuffle your deck. (You can't use more than 1 GX attack in a game.)
