Balemurk Leech

The interesting thing about this drain engine is what it counts. Eerie fires on two distinct triggers glued together: any enchantment you control entering, and fully unlocking a Room. Those two clauses interlock in a way that rewards the way Rooms are played out over time. Cast a Room and it enters as an enchantment, tripping the first clause for a point of life loss. Later, when you pay to open the far door and fully unlock it, the second clause fires for a second point, no new permanent required. The deck that runs this Leech gets two events out of a single Room, spaced across as many turns as it takes to save up the unlock cost. It is a two-mana body designed to reward a deck that treats enchantments as a resource stream rather than a set of permanents, turning every commitment into a point of reach. The drain does nothing you can see across the board: no evasion, no scaling with enchantment count, just one life per qualifying event, repeated. That flatness is deliberate. It rewards volume, not size, pushing the deckbuilder toward cheap enchantments and Rooms whose staged unlocks each pay out twice. It sits in a long line of black creatures that convert a triggered permanent event into opponent life loss, but where the aristocrats counted deaths, this one counts the act of committing enchantments to the battlefield. A clock that only exists if the rest of the deck is built to feed it.
