Ecstatic Awakener // Awoken Demon

The whole design turns on a single, gated conversion: pay , feed it a creature, and in one activation you draw a card and flip the 1/1 into a real threat. The draw is the dependable half, the steady graveyard-feeding value black aristocrat shells always want, but the transform is the payoff the front face keeps advertising. The once-per-turn clause is what keeps this from being an engine you spin freely; you get one conversion window a turn, and because the flip resolves off that same first activation, there is no long grind toward the reward. The upgrade is immediate the moment you have three mana and a creature to spare. What separates it from the usual sacrifice-for-value one-drop is that the payoff is a body upgrade rather than an incidental token or a drain trigger, which answers a chronic weakness of these engines: they tend to convert a board into cards and then have nothing left to close with. The catch is the three-mana price against a fragile 1/1 that has to survive the early turns before it earns its flip, and the fact that the whole plan is dead without fodder to eat. That makes it a specialist: sharp when the surrounding cards manufacture creatures to sacrifice, inert when they do not.
