Thassa, Deep-Dwelling leads a blink-based control deck that repeatedly flickers its own creatures at the end of each turn to replay powerful enter-the-battlefield effects, generating card advantage, stealing opponents' permanents, and bouncing threats back to their owners' hands. The deck builds board control through a Wizard tribal subtheme, with untapped Wizards used to counter spells on demand, while extra turn spells, mass bounce effects, and Island-count-scaling board wipes keep opponents in check. The primary win condition is an infinite turns loop using Archaeomancer to recur extra turn spells by blinking it each end step with Thassa, locking opponents out of the game entirely. I use animators like March of the Machines to turn opposing noncreature artifacts into creatures. This makes them vulnerable to my creature removal, creature bounces, and temporary theft effects. I then use Thassa, Deep-Dwelling's blink ability at my end step on those stolen pieces to gain permanent control of them.
