Bell Borca, Spectral Sergeant
A body whose power is a running tally of top-of-library gambles: this is impulse-draw as a threat, not just as card advantage. The upkeep exile is the familiar red-white engine (see the top card, play it or lose it that turn), but the twist is that the mana value of everything exiled this turn also sets Bell Borca's power, and not just the cards it exiles for you. The greatest number noted this turn is what matters, so any effect that puts cards into exile with a mana value attached can spike the size on demand: your own cascade, an opponent's flicker, a mass-exile removal spell that clips a big permanent on the way out. It reframes the whole board as ammunition, turning cards leaving play into a number attached to a 5-toughness attacker that can suddenly hit for the cost of the largest thing anyone exiled. The toughness is the anchor that keeps it relevant on turns when nothing expensive gets banished; the power is deliberately volatile, swinging from a 0 to something enormous depending on what the turn cycle happens to expose. That volatility is the point. Most creatures that scale off external events want you to build a dedicated engine; this one wants you to notice that exile is happening constantly, in every game, from both sides of the table, and to weaponize a resource everyone else treats as bookkeeping.
