Moldering Gym // Weight Room

Because each half unlocks independently at sorcery speed by paying its own cost, this reads as a curve rather than a choice: crack the door early for a tapped basic when you need the fixing, then bank the half as a payoff you cash in once the game has opened up. That deferred door carries the heavier design load. Manifest dread digs two cards deep and lets you keep the better one as a facedown 2/2, and dropping three +1/+1 counters onto that mystery body turns it into a 5/5 with a genuine chance of being a real creature underneath. Splitting a fixing effect and a threat-generator across a two-part enchantment lets one permanent behave like ramp early and a finisher late, without ever committing you to which mode matters first. The nine total mana value is a bookkeeping figure, not a bill you settle at once; the halves come out separately, on your own schedule, which is what makes an otherwise modest pile of effects worth a single card slot. And because the cheaper door stands entirely on its own, the second half rewards patience without punishing its absence: you are never stranded holding dead text while you scrape together the mana for the manifest. The Room structure is doing the real work, using timing and independence to smuggle two unrelated jobs into one slot.
