Fateful Handoff

Black's draw effects have always carried a body tax: a life payment, a discard, a permanent fed to the graveyard. This one asks for something stranger. The artifact or creature you cash in does not die or return to your hand; it walks across the table, alive and functional, onto an opponent's side of the board. That donation clause turns a card-advantage spell into a genuine deckbuilding puzzle: the more mana value you feed it, the more cards you draw, but the bigger the gift you hand your opponent. The trick is that you get to decide what "expendable" means. A creature that has already dealt its damage or triggered its enters-the-battlefield effect, an artifact whose sole job was to tap for a burst you no longer need, a big body you have already extracted the value from: these convert cleanly, and the higher the target's mana value, the fatter the payout. It sits in the lineage of controlled-giveaway effects like Harmless Offering and Donate, where handing an opponent a permanent is the point rather than the drawback, but it fuses that mechanic to raw card flow instead of a combo payoff. The cost is not paid in life or cards; it is paid in board position you have judged worthless to the recipient. Getting the trade right, a high mana value married to a battlefield presence the new controller cannot exploit, is the entire exercise.
