Ovinomancer

A repeatable unconditional kill spell stapled to a 0/1 body, with two costs deliberately stacked to keep it honest: a punishing entry tax and a self-bouncing activation. The land-return clause is the first wall. To keep the Wizard around at all you have to set your own development back by three basic lands, picking them up off the battlefield and stuffing them back in your hand. Your card count stays even, but the tempo cost is brutal: you have effectively undone three turns of land drops the moment it lands. The second wall is the activation itself: bouncing the creature to its owner's hand means you replay it (and pay the land tax all over again) every time you want to fire it. That loop is what balances hard removal on a 0/1 frame; the destroy is clean and beats regeneration, but you are taxed on the entry and the reset every single cycle. The Sheep token is the flavor signature and the joke that names the card: the victim's controller does not just lose a creature, they get a 0/1 farm animal in its place, the wizard having literally turned the target into livestock. As a piece of vintage blue gimmick design it endures, a removal engine balanced not by rate but by the friction of having to repeatedly dismantle and rebuild your own mana base to use it.
