Oloro, Ageless Ascetic + Nadir Kraken + Ashnod's Altar + Prosperous Innkeeper

Oloro, Ageless Ascetic

Nadir Kraken

Ashnod's Altar

Prosperous Innkeeper

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, Prosperous Innkeeper's second ability 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 uses Nadir Kraken as your engine to turn card draw into a growing creature token, while Prosperous Innkeeper quietly translates that creature's arrival into precious life gain. That life gain instantly awakens Oloro, Ageless Ascetic, whose triggered ability lets you pay a single mana to draw a card and drain your opponents, which loops right back into feeding the Kraken. Meanwhile, Ashnod's Altar stands ready to sacrifice the newly minted Tentacle token to fuel the mana costs required to keep this endless cycle spinning.
