Magus of the Scroll
The Magus subcycle's job was to fold famous artifacts into red and green creature shells, and this one inherits the strangest baggage of the lot: a permanent whose damage is gated behind a coin-flip you build into your hand. Cuombajj Witches deals its damage on a clean tap; this asks you to name a card, then trust that the random reveal from your grip actually hits that name. The activation reads as a repeatable Shock with a tax, but the real constraint is information management. Empty your hand to a single card and the reveal becomes deterministic: the last card you hold is the card you name, and the randomizer has nothing to choose against. That is the design tension the original Cursed Scroll resolved the same way, and the body inherits it faithfully: a fragile 1/1 whose three-mana activation only turns reliable once you have run out of options, which is precisely when an aggressive deck wants reach the most. Against a full grip the odds are miserable and the tap-plus-three rate punishes you for the privilege; in topdeck mode it becomes a clock that bleeds the empty board on both sides. The hellbent structure is the whole pitch. It was built as a payoff for the player who has already committed to spending everything, a curiosity whose reliability runs inversely to the resources you have left.
