Kecleon

It can freely change its body's color. The zigzag pattern on its belly doesn't change, however.

Poke-BODY — Camouflage: If any basic Energy card attached to Kecleon is the same type as the Attacking Pokémon's type, any damage done by attacks from that Pokémon to Kecleon is reduced by 40 (after applying Weakness and Resistance).

Blind Scratch (60): Flip a coin. If tails, this attack does no damage to the Defending Pokémon. Instead, this attack does 20 damage to 1 of your Pokémon. (Don't apply Weakness and Resistance for Benched Pokémon.)
