Bob

When Bob enters, exile another nontoken creature you control and put 3 time counters on it. If it doesn’t have suspend, it gains suspend. Create a token that’s a copy of that creature, except it has “When you cast a spell with the same name as this token, exile this token.” and it’s a Doppelganger in addition to its other types. When Bob leaves the battlefield, exile all Doppelganger tokens you control. Fire Walk With Me — {R}{R}: Exile Bob. Return it to the battlefield under its owner’s control at the beginning of your next upkeep. Activate only as a sorcery.
