Dazzling Angel

The lifegain trigger here is deliberately narrow: it only cares about other creatures entering, so it never counts itself, and it fires on every body that lands rather than on any token that dies. That framing points it at go-wide white, where each creature resolved in a turn stacks a fresh life gain rather than each combat step or each attacker. White has been printing this incremental-drip lineage at common and uncommon for decades: effects that say you control creatures, so gain a little life, and reward flooding the board over any single big play. A 2/3 flyer for three mana is a reasonable body on its own, which is the point: the card contributes to the very board state it feeds off, and unlike an enchantment that does nothing but count, it can pressure a stalled ground or trade in the air while the life total climbs. The gain is tiny per trigger and moves nothing on the battlefield, so the card lives or dies on how many creatures a deck can chain into play alongside it. Built for a token-and-anthem shell that wants a soft clock against aggression, it is the sort of role-player a set uses to give an aggressive white archetype a way to grind rather than a way to close.
