Callaphe, Beloved of the Sea

Legendary Enchantment Creature — Demigod • Mana cost: {1}{U}{U} • Theros Beyond Death • Uncommon

Callaphe's power is equal to your devotion to blue. (Each {U} in the mana costs of permanents you control counts toward your devotion to blue.)
Creatures and enchantments you control have "Spells your opponents cast that target this permanent cost {1} more to cast."
