Atraxa, Praetors' Voice - Intelligence

Atraxa turns every end step into a selective counter-multiplication event, advancing creatures, planeswalkers, artifacts, Sagas, players, and alternate-win engines without spending another card.

Atraxa triggers at the beginning of your end step and must be present as that step begins. Removing Atraxa after the trigger exists does not normally remove that trigger.

Proliferate chooses any number of eligible permanents and/or players during resolution. Hexproof and shroud do not stop a player or permanent from being chosen this way.

Any number includes zero, so a player can resolve a proliferate event without choosing permanents or players.

Proliferate can choose permanents on the battlefield and players with counters, but it cannot choose cards in hand, graveyard, exile, library, command zone, or on the stack.

A chosen permanent or player receives one additional counter of each kind already there, not one selected kind under older text.

Atraxa cannot establish the first counter on a permanent or player through proliferate.

State-based actions remove paired +1/+1 and -1/-1 counters before later proliferate decisions see the remaining counters.

Selected players receive another counter of each kind already on them, including poison, energy, experience, rad, ticket, or future supported player counters.

Atraxa can multiply poison counters after they exist, but Atraxa does not inherently have infect or toxic and does not create the first poison counter.

Proliferating a planeswalker adds loyalty counters but does not activate loyalty abilities or bypass loyalty-activation limits.

Adding lore counters can trigger chapters, but it can also rush a Saga to its final chapter and sacrifice.

Adding defense counters normally makes a battle harder to defeat, so battles are not automatic Atraxa synergies.

Each counter kind needs polarity and card-specific handling. Duplicate keyword counters usually do not add another useful copy of the keyword.

Copying Atraxa's trigger creates another proliferate event. Extra turns and additional end steps create more Atraxa triggers only when Atraxa is present as each end step begins.

Blinking Atraxa protects or resets her but does not itself proliferate. A phased-out Atraxa will not trigger at the beginning of the end step.

Use Hardened Scales, Branching Evolution, Conclave Mentor, Corpsejack Menace, Kami of Whispered Hopes, and Breed Lethality retain cards to grow creatures before Atraxa multiplies them.

Build around loyalty counters with Teferi, Tamiyo, Vraska, Ajani, Nissa, Narset, Ugin, Oath of Teferi, The Chain Veil, Ichormoon Gauntlet, Deepglow Skate, and Doubling Season.

Seed poison with Glistener Elf, Blighted Agent, Skrelv, Venerated Rotpriest, Ichor Rats, Prologue to Phyresis, Vraska's Fall, Infectious Inquiry, or toxic creatures, then multiply only the right players.

Use The Ozolith, Resourceful Defense, Ozolith, the Shattered Spire, Nesting Grounds, Power Conduit, Hex Parasite, Goldberry, Walking Ballista, and Hangarback Walker to preserve or convert counters.

Use proliferate only when lore-counter acceleration helps the chosen Saga or when counter-transfer/removal keeps timing under control.

Use charge, storage, brick, hour, tower, oil, and other normalized counter types on artifacts, lands, and players.

Use Atraxa's Phyrexian identity as flavor and support context, then include only Phyrexian cards that seed, multiply, protect, or spend counters.

Preserve the original precon identity and quantities, then convert cards by lane: retain, cut, add, or role-change depending on +1/+1, poison, superfriends, artifact-counter, or control focus.
