When The Swarmweaver enters, create two 1/1 black and green Insect creature tokens with flying.
Delirium — As long as there are four or more card types among cards in your graveyard, Insects and Spiders you control get +1/+1 and have deathtouch.
Flood the board with Insect and Spider tokens, then flip on Delirium to turn the whole swarm into +1/+1 deathtouch attackers that trade up and swing for lethal. Early turns you fuel the graveyard with diverse card types (creatures, lands, artifacts, enchantments, instants, sorceries) via self-mill and sacrifice, then go wide and overrun.
Add reliable Delirium enablers (Mesmeric Orb, Satyr Wayfinder, fetchlands, cycling lands) so the anthem comes online by turn three or four. Layer in token doublers (Doubling Season, Parallel Lives) and a closing overrun (Craterhoof Behemoth, Triumph of the Hordes) for explosive finishes, plus Skullclamp and Grim Hireling for grind. Round out with protection like Heroic Intervention and a sacrifice-value subtheme to insulate against board wipes.
