Deathbonnet Sprout // Deathbonnet Hulk

A one-drop that turns your own graveyard into a payment schedule. The front face mills you each upkeep, but the transform condition asks for three creature cards specifically, not just any three cards, which means the Sprout is quietly steering how you fill your yard: creature-heavy decks flip it early, spell-heavy ones may stall it for turns. That gate is the whole design tension. It reads like passive self-mill, but it is really a threshold engine dressed as a mana dork's body. Once it flips, the Hulk reverses the polarity: instead of feeding a graveyard it starts eating one, exiling a card each upkeep and growing only when that card is a creature. So the same resource the front face was accumulating becomes fuel the back face burns, and the incidental graveyard hate is the payoff for having built one in the first place. It sits in a small lineage of double-faced Fungus cards whose front is a slow enabler and whose back is the reward, but the specific loop here (mill to enable, then exile to grow, with creature cards as the currency on both sides) makes it a self-contained arc rather than a static threat. The friction is that both halves want the same thing (creatures in graveyards) while pulling in opposite directions on whether those creatures stay there.
