Burning-Rune Demon
A tutor that lets your opponent decide which half of the deal you actually get. The demon fetches two cards with different names, reveals both, and hands the choice to an opponent: the one they pick lands in your hand, the loser goes to the graveyard. That single line of asymmetry reframes the whole search. A normal tutor lets you grab your best card; this one punishes greed, because if you name two bombs your opponent gives you the worse one and buries the other. The design's real reward is in the gap between the two picks. Fetch a card you want in hand and a card you want in the graveyard (a reanimation target, a flashback spell, something with an escape or delve payoff) and both outcomes serve you: the opponent's "choice" collapses into a coin you win either way. The 6/6 flying body means the tutor is never the whole point; you get a real threat attached to the puzzle. This is the black tutor for players who would rather build a two-card lock than pay full retail for a single wish. The friction lives entirely in the opponent's decision, and the deckbuilding challenge is engineering that decision so it no longer matters which way it falls.
