Oloro, Ageless Ascetic + Nadir Kraken + Ashnod's Altar + Blood Artist

Oloro, Ageless Ascetic

Nadir Kraken

Ashnod's Altar

Blood Artist

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. Activate Ashnod's Altar by sacrificing the Tentacle, adding CC.
4. When the Tentacle dies, Blood Artist triggers, causing you to gain 1 life and target opponent to lose 1 life.
5. Oloro's second ability triggers, causing you to pay 1 to draw a card and cause each opponent to lose 1 life.
6. Repeat.

This insidious loop feeds on itself by transforming the simple act of drawing a card into a self-sustaining engine of growth and attrition. As you draw, Nadir Kraken rewards the action by spawning a Tentacle token, which you can immediately sacrifice to Ashnod's Altar to generate the colorless mana needed to keep the chain moving. The token's demise triggers Blood Artist to drain your opponents while padding your life total, which in turn awakens Oloro, Ageless Ascetic to let you pay a single mana to draw yet another card—seamlessly looping the entire process into an overwhelming cascade of life, death, and card advantage.
