Yes Man, Personal Securitron

The genius of this design is that it weaponizes the give-away. Handing an opponent a creature is normally the province of curses and drawbacks (Donate, Harmless Offering), but here the gift is the engine: every time you tap it, you shove the 2/2 across the table, draw two cards, and stamp a quest counter on it. The draw and the counter fire on "when they do," so the payout is tied to the transfer completing, not the tap: if the target becomes illegal and the ability fizzles, you get nothing while the creature sits tapped, so the attempt was never free. Then the bind reverses. Ownership never changes, but control does, and control is what gates the tap. Once the opponent has it, only they can activate it, and doing so simply loans it off to one of their opponents while netting them two cards. Their alternatives are to leave a robot they never asked for sitting inert, or to kill it and hand you a tapped Soldier army sized to how many times the loan cycled. Wild Card triggers on leaving the battlefield and pays the owner, so the tokens come home no matter whose side it dies on. The your-turn-only restriction keeps the initial loop tethered to whoever benefits. Most cards that donate a permanent are trying to inflict something; this one turns the transfer into a metronome, ticking up a payout while it digs whoever activates it deeper into the deck.
