Mimikyu

When Mimikyu enters the battlefield, put a
Disguise counter on it.
If Mimikyu would be put into a graveyard from
the battlefield while it has a Disguise counter on
it, instead tap Mimikyu and remove the Disguise counter from it.
A lonely Pokemon, it conceals its terrifying appearance beneath an old rag so it can get closer to people and
other Pokemon.
