Blood Scrivener
The conditional baked into this Zombie Wizard inverts the usual cost of an empty hand. Hellbent, as a design idea, treats an empty hand as a threshold to be rewarded; this card treats it as a draw engine, turning the moment you have nothing to lose into the moment your next draw doubles. The trick is the window. The replacement effect only applies while your hand is genuinely empty, so the bonus card arrives precisely when most decks are starved, then disappears again the instant you stabilize. That makes it a self-correcting throttle: refill your hand and the effect switches off, run yourself dry and it switches back on, all at a one-life tax per draw. The friction lives in that life payment and in the narrowness of the condition the effect checks, which is why the card asks for a deck built to empty its hand on purpose rather than one that merely happens to. The 2/1 body is the rest of the bargain: a real clock that wants to dump cards onto the board fast, the kind of aggressive shell that arrives at an empty hand early and turns each subsequent topdeck into two. It is a draw-two stapled to a creature, but only for the player willing to live with the empty hand most opponents spend mana trying to avoid.
