Lyla, Holographic Assistant + Basking Broodscale + Smothering Abomination

Lyla, Holographic Assistant

Basking Broodscale

Smothering Abomination

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. Activate the Eldrazi Spawn by sacrificing it, adding C.
5. When the Eldrazi Spawn dies, Smothering Abomination triggers, causing you to draw a card.
6. Repeat from step 2.

This loop is an exquisite feedback engine where drawing a single card kicks off a self-sustaining cycle of growth and sacrifice. Lyla, Holographic Assistant bridges the gap by turning every drawn card into a +1/+1 counter that triggers Basking Broodscale, instantly spawning an Eldrazi Spawn token to feed the engine. That token is then sacrificed for mana, which conveniently satisfies Smothering Abomination's upkeep requirement while its triggered ability draws you another card to restart Lyla, Holographic Assistant all over again.
