This is a Golgari lifegain tribal-counters deck: Blech turns every instance of lifegain into a +1/+1 counter on each Pest, Bat, Insect, Snake and Spider, so the deck floods the board with Pest and Insect tokens and pairs them with many small, repeatable life triggers. Creature-entry and death triggers, attack triggers and landfall all gain life. Counter doublers multiply each Blech trigger, and drain effects turn the same lifegain into direct damage. Sacrifice outlets recycle the tokens, whose death triggers feed more lifegain, cards and growth. How it wins: It swarms with counter-laden Pests, Insects and Bats that are given trample, menace or deathtouch, while every lifegain trigger also pings each opponent, so combat and drain close the game together. Key roles: - Tribal token producers: These generate Pests, Insects, Spiders and Bats that Blech grows. Many of the Pests also gain life when they attack or die, which fuels the next round of counters. (Beledros Witherbloom, Scute Swarm, Pest Summoning) - Incremental lifegain triggers: Creatures entering, attacking, landfall and spells cast each gain a point or two, so Blech fires many times a turn. Some cards boost every gain by one. (Bogwater Lumaret, Pest Rescuer, Prosperous Innkeeper) - Counter amplification: Counter doublers add extra counters to every Blech trigger. Other cards turn counters into trample, extra Insect tokens or card draw. (Winding Constrictor, Hardened Scales, Iridescent Hornbeetle) - Lifegain drain: Several permanents make opponents lose life whenever life is gained, turning the lifegain engine into a reach win condition beside combat. (Dina, Soul Steeper, South Wind Avatar, Starscape Cleric) - Sacrifice and death value: Sac outlets and death payoffs turn dying tokens into life, drains, cards, recursion and fresh Pests. That keeps the board refilling and protects against wipes. (Cauldron of Essence, Moldervine Reclamation, Blight Mound) - Pest combat finishers: Anthem and evasion effects for attacking Pests and the whole team turn a wide, grown board into lethal attacks. (Feral Appetite, Blossoming Bogbeast, Root Manipulation)
