Tidus

Tidus is a Bant (+1/+1 counters/proliferate) Commander deck in white, blue, and green. Its main game plan is to stack counters quickly, then multiply them with proliferate and doubling effects to build an overwhelming board.

Key synergies include Hardened Scales, Conclave Mentor, Branching Evolution, Doubling Season, Vorinclex, and Ozolith effects to supercharge counter growth, while Evolution Sage, Thrummingbird, Grateful Apparition, Flux Channeler, Inexorable Tide, and Tekuthal repeatedly proliferate. Creatures like Walking Ballista, Hangarback Walker, Stonecoil Serpent, Mikaeus, the Lunarch, and Incubation Druid scale especially well with all the extra counters.

The deck wins by snowballing into huge, resilient creatures, generating value from counter-based engines, and often finishing through massive combat damage or a lethal Walking Ballista. A strong suite of ramp, protection, and premium interaction/countermagic helps it establish and protect its board while it grows out of control.
