Pokémon Trading Card Game - Mew - EX: Legend Maker 10

Poké-Power: Type Change
Once during your turn (before your attack), you may choose 1 of the Defending Pokemon. Mew is the same type as that Pokemon (all if that Pokemon is more than 1 type) until the end of your turn. This power can't be used if Mew is affected by a Special Condition.

Link Blast 50
If Mew and the Defending Pokemon have a different amount of Energy attached to them, this attack's base damage is 20 instead of 50.
