Atraxa Frostlock

Atraxa Frostlock is a 4-color control/proliferate Commander deck in white, blue, black, and green built around Atraxa, Praetors’ Voice. Its main plan is to slow the table down with tap/freeze effects and enchantment-based lockdown pieces, then use proliferate to keep those stun counters and tempo effects going longer.

Key synergies include cards like Frost Breath, Sleep, Hands of Binding, Bubble Snare, Claustrophobia, Encrust, and Numbing Dose to lock creatures down, while Atraxa, Thrummingbird, Experimental Augury, Contentious Plan, Steady Progress, and Thirsting Roots help proliferate counters and extend the disruption. The deck backs this up with solid control tools, removal, sweepers, and ramp.

It generally wins by grinding opponents out of combat, controlling the board, and eventually taking over with Atraxa and value creatures while opponents struggle to untap or keep threats online.
