The Legend of Kuruk flips into Avatar Kuruk once its third chapter resolves; Baboon Spirit exiles the Avatar mid-activation and returns it as the saga at end of turn, resetting the lore counter engine. Karn's Bastion proliferates the saga to chapter III on demand, closing the loop and taking the table hostage one extra turn at a time.

Move to your next turn. At the beginning of your precombat main phase. The Legend of Kuruk triggers, putting a lore counter on it. Its second chapter ability then triggers, causing you to scry 2 and draw a card.
Activate Karn's Bastion by paying and tapping it, causing you to proliferate and put a lore counter on The Legend of Kuruk.

Result

Infinite turns; Lock

Variations

Cheaper, tighter, alternate lines

The combo requires all three pieces on the battlefield simultaneously, which makes it fragile to removal at multiple points — any response to Karn's Bastion activation or Baboon Spirit's trigger breaks the chain. Swiftfoot Boots or Padeem, Consul of Innovation protect Baboon Spirit, the most critical piece to keep alive; without it, the loop has no way to recycle the Avatar.
