This deck floods the board with cheap creatures of power 2 or less, mostly enter-the-battlefield value bodies and Snakes. Each one gives Ezuri, Claw of Progress an experience counter, and at every combat Ezuri dumps that growing pile of +1/+1 counters onto another creature it chooses. Because the counters are permanent, the stream of small creatures turns into one or more huge threats. Card draw on combat damage and evasion convert those threats into cards and lethal attacks, backed by a Simic toolbox of flash creatures, counters and removal. How it wins: It pumps a creature with Ezuri's experience counters, makes it evasive or tramples it over with team pumps, and kills through combat damage, sometimes halving a life total with Scytheclaw or swinging the whole board with Overrun or Beastmaster Ascension. Key roles: - Experience fodder: Low-power creatures, especially those that draw cards, fetch lands or recur spells when they enter, each give Ezuri, Claw of Progress an experience counter while paying for themselves. (Coiling Oracle, Elvish Visionary, Wistful Selkie) - Snake and token swarm: Cards that make several small creatures at once add experience counters in bursts, give Kaseto bodies to pump, and widen the board for team-wide pumps. (Patagia Viper, Orochi Hatchery, Thelonite Hermit) - Counter payoffs: Creatures and lands that add or scale with +1/+1 counters stack on top of Ezuri, Claw of Progress's growth, and a big body later fuels large card draws. (Prime Speaker Zegana, Forgotten Ancient, Novijen, Heart of Progress) - Evasion and connection: Unblockability, flying, islandwalk, trample and haste equipment make sure the creature carrying the counters actually hits a player. (Kaseto, Orochi Archmage, Sword of Vengeance, Cold-Eyed Selkie) - Combat-damage card engine: Creatures and artifacts that draw on combat damage, plus ninjutsu tricks, refill the hand whenever the pumped creatures connect. (Bident of Thassa, Ninja of the Deep Hours, Broodbirth Viper) - Finishers and interaction: Team pumps and life-halving close games, while flash creatures, counterspells and removal guard the board and answer threats. (Overrun, Scytheclaw, Mystic Snake)
