Callous Oppressor

Control magic that hands the opponent a veto, then taps itself indefinitely to keep what it steals. The opponent's declaration as it enters carves out the only bodies you can never touch: a sharp opponent picks whatever covers their best threat, leaving you to govern whatever else is on the table. Every theft costs the tap, and the stolen creature reverts the instant the Octopus untaps, so the self-defeating clause is wired straight into the engine: leave it untapped and you surrender the prize, keep it tapped and you can neither steal a second body nor push damage with the 1/2. The line letting you decline to untap exists precisely so the lock can hold across turns rather than slipping the moment your untap step arrives. The lineage is the old Control Magic and Persuasion school of blue creature theft, but reframed as a repeatable, opponent-gated tap engine: where an aura commits a card and stays put, this trades permanence for the freedom to redirect one tap across many targets. It is a creature of the tribal era in design as much as flavor, because the opponent's type choice barely dents a deck spread across many creature types and strangles a focused tribal build, which means the card's strength is dictated entirely by what it is pointed at.
