When Ezuri enters, you may pay . If you do, proliferate twice.
Whenever you proliferate, draw a card.
Build a Simic counters engine where every proliferate trigger draws cards, snowballing into an unbeatable card-advantage lead. Drop counter sources (planeswalkers, +1/+1 counters, energy, charge counters) early, then chain proliferate effects each turn to refuel your hand while growing a wide board. You close by overwhelming with massive counter-laden creatures or comboing off the draw engine.
Add free or cheap repeatable proliferate engines (Inexorable Tide, Evolution Sage, Karn's Bastion) and untappers like Pemmin's Aura plus mana doublers to build toward infinite proliferate-draw loops. Tighten the mana base with fast rocks (Sol Ring, Arcane Signet, Fellwar Stone) and add interaction (Cyclonic Rift, Swan Song, Pongify) so the engine survives. For a combo finish, include outlets like Walking Ballista or Thassa's Oracle with a way to deck yourself safely.
