Rakdos, Patron of Chaos
The devil's bargain rendered as a repeatable end-step trigger. Every turn the demon offers your opponent a choice with no good answer: give up two nonland, nontoken permanents of their choosing, or hand you two cards. The elegance is in what each restriction refuses to let them do. Nonland means they can't fluff the sacrifice off on a spare Forest; nontoken means they can't feed it a saproling or a Treasure; "of their choice" means it isn't targeted removal you get to point, so they'll always jettison their two least relevant permanents. That last clause is what keeps this fair. A version that let you pick the sacrifices would be a warping asymmetric edict; instead the opponent controls the pain, and the trade-off is honest either-or resource attrition. Against a wide, permanent-heavy board the demon strips two threats a turn; against a lean control shell with nothing to spare, it just refills your hand. Rakdos of the guild has always been the "let's both suffer" color pair, and this reading of the character leans into transactional cruelty rather than raw damage: the god of the carnival who deals in bargains, not blasts. The 6/6 flying, trample body is the closer stapled underneath, so the end-step drain is upside on a creature that already ends games. What you're paying six mana for is a demon that makes your opponent poorer on every one of your turns and cannot be answered by simply refusing to engage.
