Atraxa, Praetors' Voice is the engine of this deck, using her end-step proliferate trigger to continuously stack +1/+1 counters across the board while counter-doublers like Corpsejack Menace, Kalonian Hydra, and Vorel of the Hull Clade accelerate growth to overwhelming proportions. The deck fuels itself by converting creatures laden with +1/+1 counters into mana through Jiang Yanggu, Wildcrafter and card draw through Fathom Mage, while redundant proliferate sources keep counters compounding every turn. The win condition is combat damage from an army of enormous, evasive creatures, often granted flying through Abzan Falconer and made nearly unstoppable when Cathars' Crusade floods the board with counters every time a new creature enters.
