Azlask, the Swelling Scourge sits at the center of a strategy that floods the board with Eldrazi Spawn and Scion tokens through a dense package of enter-the-battlefield effects, sacrifice engines, and token doublers, accumulating experience counters every time a colorless creature dies to make Azlask's pump ability increasingly lethal. The deck's primary win conditions are combo-based, using Ulalek, Fused Atrocity alongside Echoes of Eternity and either Glaring Fleshraker or Spawn-Gang Commander to generate infinite copies of triggered and activated abilities, producing unlimited tokens and damage; Lithoform Engine can substitute for Echoes of Eternity in the latter line. Outside of combo, the deck can close games through a massive alpha strike enabled by Azlask's pump, backed by the indestructible and annihilator granted to the token swarm.
