Blessed Spirits

A flying 2/2 for is the kind of unremarkable body that exists mostly to carry a payoff, and the payoff here is the enchantment-cast trigger. The wording matters: it counts the cast, not the resolution, so it pays out even when the enchantment is countered, and it rewards auras and global enchantments alike rather than caring about what the spell does or where it ends up. That makes it a clean engine for the enchantments-matter shell, where the deck is already casting two or three enchantments a turn for their own value and the Spirit rides along, gaining a counter each time and turning an evasive afterthought into a real clock by the midgame. The design discipline is in what it does not do: there is no protection, no recursion, no way to convert the counters into anything but combat damage, so the card stays a fair beater that scales only as fast as your enchantment count and dies to any removal aimed at it. Its lineage is the family of "whenever you cast a [type] spell" creatures that turn a deckbuilding commitment into a growth curve, and its value tracks exactly one variable: how many enchantments the rest of the list is willing to run to feed it.
