Twisted Fealty

Threaten effects have always priced themselves against a single question: what do you do with the creature before you hand it back? Act of Treason and its descendants answer with an attack, a sacrifice, or nothing. This one splits the difference by stapling a Wicked Role to the transaction, so even a clean borrow-and-return leaves value behind: the +1/+1 makes the borrowed body hit harder, and the drain trigger fires when the Role reaches the graveyard. That trigger is worth dwelling on, because the Role can hit the graveyard by being overwritten as much as by the creature dying. Attach the token to the stolen creature, throw it at a sacrifice outlet, and the death drains for one; or attach it to your own creature to bank a slow point of reach and a permanent buff. The two halves also target independently, which quietly matters: you can seize one creature and Role up a different one, decoupling the borrow from the buff. The cost of all this is that neither half is efficient in isolation. The steal portion is priced right at the standard three-mana baseline, so you are paying nothing extra for it but also nothing for the Role: as a Role-maker alone it is overpriced against the enchantment-matters payoffs. The card's whole case rests on wanting both effects in the same turn, which is a narrower want than the text's breadth suggests.
