Ditto (Paldean Fates 201/091)

Abilities

Once during your first turn, if this Pokémon is in the Active Spot, you may search your deck and choose a Basic Pokémon you find there, except any Ditto. If you do, discard this Pokémon and all attached cards, and put the chosen Pokémon in its place. Then, shuffle your deck.

Attacks

Its transformation ability is perfect. However, if made to laugh, it can't maintain its disguise.
