This is a lifegain-and-counters tribal deck built around Blech, with the creature base kept inside Blech's tribes wherever possible: Pests, Bats, Insects, Snakes and Spiders, including on-tribe Snakes like Ikra Shidiqi, the Usurper. Small, repeated lifegain triggers (landfall life, attack triggers, death triggers, upkeep and cast triggers) make Blech put +1/+1 counters on every creature of those types, and counter doublers and adders multiply each trigger. Those same lifegain events also become direct life loss for opponents, so the deck pressures with both a growing board and drain, and it can close with a deliberate persist loop. How it wins: It swarms with growing Pests, Snakes, Insects and Spiders that pick up trample, menace and deathtouch, while drain effects that copy each life gain onto opponents, or a repeating persist sacrifice loop, finish them off. Key roles: - Incremental lifegain triggers: Many cheap, repeatable sources of 1-2 life each fire Blech's counter trigger several times per turn cycle, from lands entering, creatures entering, attacks and spells cast. (Bogwater Lumaret, Lifegift, Teacher's Pest) - Counter amplification: Effects that add or double +1/+1 counters turn each of Blech's triggers into large growth across the whole tribal board, and some turn counters into card draw. (Winding Constrictor, Doubling Season, Hardened Scales) - On-tribe creatures and tokens: Nearly every creature is a Pest, Bat, Insect, Snake or Spider so Blech grows them all, and token makers widen that board further. Several Pest tokens gain life when they attack or die, which feeds the loop again, and Ikra Shidiqi, the Usurper is a Snake that turns combat damage into life equal to toughness. (Scute Swarm, Blight Mound, Ikra Shidiqi, the Usurper) - Lifegain into drain: Payoffs make opponents lose life whenever the deck gains life, so every small gain doubles as reach toward a win outside combat. (Enduring Tenacity, Dina, Soul Steeper, South Wind Avatar) - Persist sacrifice loop: Sacrificing the Snake Persistent Constrictor brings it back with a -1/-1 counter. A death-triggered lifegain effect then makes Blech add a +1/+1 counter, the two counters cancel, and it can persist again. Each cycle drains opponents through death and lifegain triggers. Devouring Swarm is the free repeatable outlet, Phyrexian Tower and Village Rites add one-shot sacrifices, and recursion returns key creatures otherwise. (Persistent Constrictor, Devouring Swarm, Cauldron of Essence) - Evasive combat finish: Trample, menace and deathtouch granters, along with mass pump, let the oversized tribal board break through blockers and convert combat damage into more life and cards. (Duskshell Crawler, Ohran Frostfang, Blossoming Bogbeast)
