Dream Devourer

Foretell was designed to split a card's payment across turns and hide its identity face-down in exile, one spell at a time; this Demon takes that structural trick and grants it to your entire hand at once. Every nonland card without foretell gains it with its cost reduced by two, which reframes the whole turn cycle: instead of dumping mana on a single big spell, you shave two off everything and spread the payment across turns, exiling now and casting later at a discount. The cost reduction is where the real value lives, since it applies to each card independently rather than to one marquee bomb. What pays for it is the body: a 0/3 that does nothing to the board on its own and asks you to survive long enough for the tempo math to compound. The foretell trigger that pumps it +2/+0 is the design's small self-referential joke, turning a defensive shell into an occasional attacker on the turns you're stockpiling anyway, though the buff evaporates at end of turn and never touches toughness. The effect it opens up is quietly generic in the best sense: any deck full of expensive spells suddenly plays two mana cheaper if it can spare the exile mana up front, a universal discount enabler that rewards deckbuilding around the wrong end of the curve rather than around the creature itself.
