Angelic Chorus

Lifegain that scales off your own creatures was a recurring white project in this era, and the version here ties the trigger to toughness rather than power or a flat number. The choice matters: pegging the gain to toughness means defensive, durable creatures pay out the most, which keeps the engine on the side of the board white wants to occupy anyway. It rewards going wide with bodies you were already casting rather than asking you to assemble a separate combo, and the life arrives whenever a creature enters, regardless of whether it came down via casting, a token effect, or a flicker. That distinction (creatures entering, not creatures cast) is what gives the enchantment its ceiling: any deck that manufactures repeated enters-the-battlefield events turns each one into a toughness-sized life payment, and the numbers compound faster than the rate suggests. As a five-mana enchantment with no immediate board impact, it has always asked you to have already committed to a creature-heavy plan before it earns its slot. What it offers in return is a cushion that makes white's swarm strategies durable against aggression and burn, converting board presence into a resource that does not trade with removal. The template it set, lifegain as a byproduct rather than a build-around, recurs across later white enchantments that pay you for doing what your deck does anyway.
