Vengeful Possession

The Threaten effect has always been feast or famine: spectacular when there is a blocker worth stealing and a sacrifice outlet online to eat it before it goes home, and dead weight in every game where those pieces never line up. A borrowed creature you cannot profitably attack with or dispose of is a wasted card, and this class of spell has historically had no answer for the famine end. The loot rider is the fix, and it works without touching the ceiling: you still untap the target and give it haste, so the aggressive line is fully intact, but in the games where the steal-and-swing plan stalls, the discard-and-draw cycles the card toward something you can actually use. The decision happens during resolution, before you receive priority: as the spell resolves you take control of the creature and, in that same window, choose whether to pitch a card to draw one. You are betting on the value of the theft before you have swung with the borrowed body or seen a block, so the loot is a proactive smoothing of variance rather than a look-and-react option. Sorcery speed keeps it a planned tempo swing rather than an instant-speed blowout. That tacked-on card selection is why the redesign matters: a temporary-control spell built to refuse to rot in hand when the board turns against it, where every prior version simply sat there dead.
