Oloro, Ageless Ascetic

Nadir Kraken

Ashnod's Altar

Verdant Sun's Avatar

How it works

1. Draw a card.
2. Nadir Kraken triggers, causing you to pay 1 to put a +1/+1 counter on it and create a 1/1 Tentacle creature token.
3. When the Tentacle enters the battlefield, Verdant Sun's Avatar triggers, causing you to gain 1 life.
4. Oloro's second ability triggers.
5. Holding prioirty, activate Ashnod's Altar by sacrificing the Tentacle, adding CC.
6. Resolve the Oloro trigger, causing you to pay 1 to draw a card and cause each opponent to lose 1 life.
7. Repeat.

This loop transforms your standard draw step into a self-sustaining engine by turning every card drawn into a cascade of resources. When Nadir Kraken prompts you to invest mana into creating a Tentacle token, Verdant Sun's Avatar steps in to buffer your life total upon entry, which cleanly feeds Oloro, Ageless Ascetic's conditional draw-and-drain trigger. By using Ashnod's Altar to convert that very same Tentacle into a fresh influx of colorless mana, you generate the exact funds needed to keep the Kraken fed and fuel Oloro's payment cost, ultimately draining the table dry while keeping your hand perpetually full.
