Lyla, Holographic Assistant + Basking Broodscale + Doom Weaver

Lyla, Holographic Assistant

Basking Broodscale

Doom Weaver

How it works

1. Draw a card.
2. Lyla triggers, putting a +1/+1 counter on Basking Broodscale.
3. Basking Broodscale triggers, creating a 0/1 Eldrazi Spawn creature token.
4. When the Eldrazi Spawn enters, Doom Weaver's soulbond ability triggers, pairing Doom Weaver and the Eldrazi Spawn.
5. Activate the Eldrazi Spawn by sacrificing it, adding C.
6. When the Eldrazi Spawn dies, it triggers, causing you to draw a card.
7. Repeat from step 2.

This loop is a masterclass in recursive engine-building, transforming a simple card draw into an endless cascade of triggers. It starts when you draw a card, which causes Lyla, Holographic Assistant to hand a +1/+1 counter to Basking Broodscale. That counter prompts Basking Broodscale to spawn an Eldrazi Spawn token, whose very arrival lets Doom Weaver bond with it via soulbond. Sacrifice that freshly minted token for mana, and Doom Weaver's granted death trigger kicks in to draw you a fresh card—restarting the entire cycle without missing a beat.
