Thassa, Deep-Dwelling

The end-step blink defines this member of the enchantment God cycle, and it is why the 6/5 body matters least of everything printed here. Every God in the design lives as an indestructible enchantment until you clear the devotion bar, but this one spends most of the game not attacking anyway; the engine hums underneath the creature the whole time. The recurring exile-and-return is a value spigot that never asks you to hold up mana or spend a card: each end step, one of your creatures flickers, resetting its enter-the-battlefield trigger and shedding any Auras or counters pinned to it. Because it happens on your own end step rather than in response to a spell, it is a scheduled reset, not a reactive dodge; the timing is what makes it safe, arriving when opponents have the fewest levers to interact and the fewest reasons to hold up removal. That turns any creature with a worthwhile ETB into a repeatable machine on a clock you control. The tap ability is the quiet second half: a way to hold the biggest blocker or attacker off the board while the flicker grinds. The devotion clause holds the whole thing together. With fewer than five blue pips on the battlefield, this is a four-mana indestructible enchantment that still triggers every turn, which means the blink and the tap are running long before the God is ever a creature at all.
