Rapid Regeneration — The Swarmlord enters with two +1/+1 counters on it for each time you've cast your commander from the command zone this game.
Xenos Cunning — Whenever a creature you control with a counter on it dies, draw a card.
Build a wide, counter-laden Tyranid swarm that turns every death into card advantage via Xenos Cunning, then bury opponents under tokens and +1/+1 counter synergies. Early turns ramp and deploy counter-generating creatures; mid-game The Swarmlord enters bigger each recast, refueling your hand as your board trades or sacrifices into removal.
Add proliferate engines (Evolution Sage, Doubling Season) and stronger counter doublers to make every trigger lethal-adjacent. Tighten the sacrifice package with free outlets (Viscera Seer, Goblin Bombardment) and drain payoffs (Zulaport Cutthroat, Blood Artist) so deaths win the game, not just draw cards. Improve mana with fast rocks and ramp so you can recast The Swarmlord repeatedly and refill on demand.
