Devotion Payoff

Cards whose effect scales with or is gated by devotion, the count of colored mana symbols among the mana costs of your permanents. Gray Merchant of Asphodel drains for your devotion to black on entry; Nykthos, Shrine to Nyx and Nyx Lotus tap for mana equal to devotion; the Theros gods are indestructible noncreature enchantments until devotion crosses a threshold, and Master of Waves makes tokens for devotion to blue. Distinct from go-wide or artifact pip-count strategies that merely BUILD devotion without rewarding it; those are a computed mana-pip facet, not this text-detectable cares-about tag.
