Eruth, Tormented Prophet
The trade rewrites what "draw a card" costs you. Every draw becomes a two-card dig, but both cards are exiled and playable only for the rest of the turn, converting each card-draw effect into a burst of impulsive advantage that evaporates at cleanup. This is the tension that makes the prophet a build-around instead of a value engine: the selection is enormous, yet you can bank none of it, so the payoff lives entirely in casting fast enough to spend the surplus before your upkeep arrives. It wants low curves, cheap spells, and repeatable draw effects that stack multiple exiles into a single window you can actually empty. The "exile instead of draw" space has been circled before, usually as one-off impulse draw on red spells with a temporary-access clause, but bolting it to your ordinary draw step and making it a permanent replacement effect changes the texture of the whole game: your hand stops accumulating, and your turns become a race against the clock you carry with you. The 2/4 is deliberately unglamorous, a survivable blocker meant to keep the prophet alive while the real work happens on the stack. What results is a card that punishes hoard-and-grind play and forces a tempo discipline onto blue-red, the pairing most inclined to sit back and draw for value; here, drawing for value is the one thing the card refuses to let you do.
