Dirgur Focusmage // Braingeyser

As raw a draw spell as blue has ever printed, the reverse side has drifted between formats since the earliest days: refill priced by whatever mana you leave open, a variable draw with no ceiling but your untapped lands. Stapling it to a creature front changes when you reach for it. The Djinn Monk shaves a generic mana off every instant and sorcery you play, discounting the deck's whole spellbook while it holds the board. Because these are two faces of one card, you pick which to play off the top: the discounting body early, the X draw later, whichever the game asks for. The two never overlap on the battlefield, so the Monk cannot cheapen the very Braingeyser it shares a card with; the discount is for everything else the deck runs. Prepared ties the halves thematically. The charge banks when you cast a five-plus mana value instant or sorcery from hand, and it keys to a triggered ability: the state flips when that trigger resolves, then waits on other cards that care about prepared creatures. The 1/4 is a durable body meant to survive and keep discounting while a deck leans into expensive spells. This is built for a shell already committed to casting big blue: it cheapens what that deck was going to do anyway and rewards the exact sequencing (play something large, collect the charge) it naturally produces.
