Whip of Erebos

Two effects that share a color of mana and nothing else, stapled to one legendary body and made to feel inevitable. The static half is a brick of stabilization: every creature you control drains on the way through, turning a board of midrange beaters into a clock that also buys time against another aggressor. The activated half is the engine that justifies the rest of the cost. Reanimation that hands the creature back with haste, then exiles it at the next end step, means you are renting a body for one turn, not banking it. That end-step exile is what keeps the loop from snowballing into permanent recursion: the returned creature will not stick around to swing again next turn or become a repeatable resource. The replacement clause routes it to exile no matter where it would otherwise go, so you cannot bounce it to hand, slot it into a graveyard engine, or claim a death trigger by feeding it to a sacrifice outlet: exile instead of the graveyard means the creature never dies, so anything keyed on "dies" stays silent. Leaves-the-battlefield triggers are a different animal and still fire, since exile is a departure from the battlefield: a returned creature with such a trigger gives it to you on the way out. What you actually buy is the swing. You attack with the rented body, you drain with it thanks to the lifelink the Whip is already granting, and then it goes. It reads like a value enchantment and plays like a haymaker, with the sorcery-speed restriction denying the instant-speed blowout that would make the rental too cheap.
