Hapatra

This is a mono-blue Commander control/value deck built around Hapatra, the Desert Frost, leaning into flicker/blink, proliferate, and tempo interaction.

Its main game plan is to control the board with bounce, counters, and blue removal, while repeatedly blinking value creatures like Aether Channeler, Venser, Shaper Savant, Barrin, Tolarian Archmage, Man-o'-War, and Exclusion Mage for repeated disruption. A strong subtheme is proliferate, using cards like Thrummingbird, Flux Channeler, Tekuthal, Inexorable Tide, Tezzeret’s Gambit, and Experimental Augury to grow counters on permanents such as Ichormoon Gauntlet, Midnight Clock, Everflowing Chalice, The One Ring, and any commander-related counters.

It usually wins by grinding out value and locking up tempo, then finishing with big threats like Hullbreaker Horror, Tolarian Terror, Hall of Storm Giants, or through overwhelming advantage from repeated blink/proliferate synergies.
