Identity Thief

Creature — Shapeshifter

Whenever this creature attacks, you may exile another target nontoken creature. If you do, this creature becomes a copy of that creature until end of turn. Return the exiled card to the battlefield under its owner's control at the beginning of the next end step.

Identity Thief exiles a nontoken creature until end of turn and enters as a copy of it — meaning you get that creature's triggered abilities, attack triggers, and enters-the-battlefield effects on demand, every turn you untap. The cost is real: four mana, only one body, and it blanks against token-heavy boards — but the ceiling is absurd, because copying something like Medomai the Ageless with Obeka, Brute Chronologist in play turns a single swing into an infinite extra-turn loop.

Obeka, Brute Chronologist

58.7% of decks · synergy 0.57

Identity Thief is a centerpiece in Obeka, Brute Chronologist decks because copying an extra-turn creature like Medomai the Ageless and then having Obeka end the turn before the 'you don't untap' clause resolves produces a repeatable loop — Obeka handles the cleanup, Identity Thief handles the value.

Kamiz, Obscura Oculus

Kamiz, Obscura Oculus

15.3% of decks · synergy 0.15

Kamiz, Obscura Oculus makes one attacker unblockable each combat, and Identity Thief copying a high-value creature gets that free swing while also triggering whatever the copy brings — it's a repeatable way to weaponize attack triggers on a body that's already getting through.

Identity Thief is a Commander card through and through — the multi-player environment gives it a wide target selection, and the format's abundance of creatures with powerful attack or ETB triggers means the copy ability is almost always relevant. In Legacy, Modern, and Pioneer it's legal but ignored; four mana for a creature that does nothing the turn it arrives is far too slow for those formats' threat density. Vintage has the same problem at a higher power ceiling. Commander is where the pieces align: slower games, juicier targets, and commanders like Obeka, Brute Chronologist that turn Identity Thief's trigger window into a combo engine.

Pricing data isn't available at the moment, so check Scryfall or your preferred retailer for a current number. Given that Identity Thief is a niche combo piece with a narrow but devoted home in Obeka builds, it tends to sit in the budget-to-moderate range — worth grabbing a copy if you're building the deck rather than waiting.
