Lyla, Holographic Assistant + Kindred Discovery + Basking Broodscale

Lyla, Holographic Assistant

Kindred Discovery

Basking Broodscale

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 creature token enters, Kindred Discovery triggers, causing you to draw a card.
5. Repeat from step 2.

This ingenious loop begins turning when you draw a card, which causes Lyla, Holographic Assistant to place a +1/+1 counter on Basking Broodscale. Because Basking Broodscale responds to receiving a counter by creating an Eldrazi Spawn token, that new creature's entry triggers Kindred Discovery (with Eldrazi chosen as the creature type) to draw you another card, restarting the entire cycle. The engine feeds itself endlessly, letting you churn through your deck while generating an army of tokens and massive counters.
