Strength from the Fallen

Two engines in one enchantment, and the trick is that they feed each other. The constellation trigger reads off the count of creature cards in your graveyard, which means every enchantment you play after this becomes a recurring pump effect whose size scales with how thoroughly you have filled the yard. That ties together two strategies that normally pull in opposite directions: enchantment density, which wants permanents stockpiled on the battlefield, and self-mill or aggressive trading, which wants bodies in the bin. A deck that mills itself or chump-blocks freely turns each subsequent enchantment drop into a +5/+5 or larger swing the moment it resolves, since the trigger fires when the enchantment enters, no activation cost or tap required. The boost lasts only until end of turn, which is the restriction doing the work: this is not a static anthem but a one-turn detonation timed to your own main phase, where enchantments are cast, so the payoff lives in precombat setup feeding the same turn's attack rather than in reactive grinding across the table. It treats dead creatures as ammunition instead of loss, the kind of graveyard-as-resource green deck that was unusual when this style of card first appeared. The ceiling is real (a yard with eight or ten creatures makes the next enchantment a kill from nowhere), but the floor is honest too: with an empty graveyard it does nothing at all, and that conditionality is what keeps a repeatable pump from being oppressive.
