A 3-mana Golgari legend from Teenage Mutant Ninja Turtles that demands a sacrifice or a discard every time it attacks or blocks — a built-in cost that rewards a deck already spending both resources.
Aristocrats and sacrifice decks. A token or expendable creature is the ideal payment for the combat cost, turning what looks like a drawback into a free additional sacrifice trigger every combat.
Discard and madness decks. A hand full of cards that want to be discarded anyway makes the cost close to free while still enabling combat.
Value-body aggro. As a 3-mana body willing to attack or block every turn, it's a reasonable rate even setting the drawback aside, in a deck that can pay it comfortably.
How it does in Commander
As the commander
It's a workable commander for a dedicated Golgari Aristocrats deck, since guaranteed sacrifice fodder in the 99 keeps the combat cost from ever being a real liability — but it's just as playable as a support piece in a deck led by something else.
In the 99
A cheap, aggressive body that fits naturally into any Golgari sacrifice or discard shell, where the drawback is closer to an upside.
Formats it's strong in
Aristocrats decks. Token generators and death-trigger creatures turn the sacrifice cost into a repeatable engine rather than a real loss.
Madness and discard decks. Cards that want to be discarded make the alternative cost essentially free most turns.
Formats it's weak in
Decks with no sacrifice fodder or discard fodder. Without either resource to spend, the combat cost eventually forces a real sacrifice of something the deck needs.
Grindy games that outlast the fodder supply. A long game can eventually exhaust a deck's supply of expendable permanents or discardable cards, turning a free cost into a real one.
Synergistic cards
Bitterblossom — A steady supply of expendable tokens that keeps the combat cost free indefinitely.
Zulaport Cutthroat — Turns each sacrifice paid for combat into direct drain damage on top of the attack itself.
Faithless Looting — Fills the hand with discardable cards while also filling the graveyard, giving the discard side of the cost a use.
Any death-trigger creature — A creature that wants to die anyway is the ideal thing to feed the combat cost every turn.
Is it worth the price?
As a recent-set card, Bebop & Rocksteady is inexpensive and a reasonable pickup for a Golgari Aristocrats or discard deck — low financial risk for an aggressive, on-theme body.
