Churning Eddy

Two bounces stapled to one card, but the second target is the catch: sending a land back alongside the creature turns a tempo play into something closer to a mini-Time Walk against a stumbling opponent. The creature half is the obvious payoff; the land half is the wrinkle that makes this more than a sorcery-speed Unsummon. Bouncing a land costs the opponent their land drop for the turn if they were tapped out, and bouncing the creature strands a developed board behind a permanent they already spent mana to deploy. Sorcery speed is the price for the doubled effect: this never works as a combat trick or an end-step reset, so it asks to be cast on your own turn as a deliberate tempo swing rather than a reactive answer. The mandatory targeting is the constraint that limits when it can even be cast: with no creature on the battlefield there is no legal target, so the spell sits dead in hand against an empty board. The cost is also real in the count: returning two permanents to hand spends your card to refund two of the opponent's, so the swing is purely tempo, not advantage. Whether that tempo is worth four mana depends entirely on the table state, and that conditionality is what kept it from ever becoming a staple: a tempo card that only swings games when the opponent is already short on resources, and a dead draw when they are not.
