Mystic Redaction

The design problem here is turning discarding, an action you normally pay as a cost, into an offensive engine that grinds someone else's library. Discard has always been a resource you spend on your own end; the second ability points it outward, so every card you pitch to a rummaging effect, a madness enabler, or a looter becomes two cards off each opponent's deck. That reframing is the whole point: it wants a deck already built to throw cards away, and it converts that machinery into a mill clock without asking you to change what you were doing. The upkeep scry is the connective tissue, smoothing your draws so the outlets keep firing and sending dead cards to the bottom of your library where an outlet can no longer waste on them. What keeps it from running away is that it accomplishes nothing on its own turn without an outlet: no discard, no mill, and the scry alone will not close a game. It is a payoff that presumes an engine is already present, rewarding a deckbuilding decision made several cards earlier rather than generating value in isolation. Mill two per discard is negligible when you pitch once and lethal in a build that discards three or four times a turn, and that gap is the question the design puts to you: how far will you bend a deck toward throwing cards away before the payoff earns its slot.
