Constellation

Cards bearing the Constellation keyword ability, which triggers whenever an enchantment enters the battlefield under your control. Each enchantment entering pings off a payoff: Eidolon of Blossoms cantrips, Setessan Champion adds a counter and draws, Doomwake Giant shrinks opposing creatures, and Archon of Sun's Grace makes Pegasus tokens. Narrower than enchantments.enchantress_draw, which is the broader engine concept covering both ETB-based and cast-based card draw on enchantments; Constellation specifically requires the keyword text and fires on any enchantment entering regardless of effect, so non-draw payoffs like Grim Guardian and Forgeborn Oreads are included here.
