Oloro, Ageless Ascetic + Nadir Kraken + Ashnod's Altar + Angelic Chorus

Oloro, Ageless Ascetic

Nadir Kraken

Ashnod's Altar

Angelic Chorus

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, Angelic Chorus 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 clever loop turns your standard resource-drawing into a self-sustaining engine by tying together life, mana, and tokens. It all begins when you draw a card, which prompts Nadir Kraken to demand a single mana so it can drop a +1/+1 counter and spawn a 1/1 Tentacle creature token. The moment that token hits the battlefield, Angelic Chorus steps in to cushion your life total by granting you life equal to its toughness. That newfound life triggers Oloro, Ageless Ascetic, whose passive drain-and-draw ability provides the exact card replacement and life loss you need to keep going. Finally, Ashnod's Altar acts as the sacrificial engine, feeding you the colorless mana required to pay Nadir Kraken's upkeep while also letting you repeat the whole brilliant cycle indefinitely.
