Oloro, Ageless Ascetic + Nadir Kraken + Ashnod's Altar + Zulaport Cutthroat

Oloro, Ageless Ascetic

Nadir Kraken

Ashnod's Altar

Zulaport Cutthroat

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, Zulaport Cutthroat triggers, causing you to gain 1 life and each 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 ingenious loop transforms a simple card draw into an absolute engine of attrition, fueled passively by Oloro, Ageless Ascetic sitting comfortably in the command zone to help fund your payments with his built-in life-gain triggers. Whenever you draw, Nadir Kraken leaps into action by offering a Tentacle token and a +1/+1 counter for a single mana, which you can immediately sacrifice to Ashnod's Altar to generate the two colorless mana needed to keep the cycle going. That vanishing sacrifice triggers Zulaport Cutthroat to drain your opponents and pad your life total, which in turn satisfies Oloro, Ageless Ascetic's tax to draw another card and restart the whole cascade.
