The Watcher in the Water creates two 1/1 Tentacle tokens whenever a non-Tentacle creature dies, and Skullclamp kills any 1-toughness creature for 1 mana to draw two cards. Phyrexian Altar converts one of those Tentacles into the 1 mana to re-equip, while Leonin Shikari makes equip activations instant-speed — the restriction to opponent turns is the price of that interaction. The whole engine runs in Azorius Kraken or Voltron shells that naturally want Leonin Shikari already.
Recipe
How it works
01
Prerequisites
It is an opponent's turn. You control another creature with toughness equal to 1.
02
Steps

, attaching it to another creature with toughness equal to 1.

- Resolve the Watcher trigger, if applicable, untapping a Kraken and putting a stun counter on a permanent.
- Resolve the Skullclamp trigger, causing you to draw two card.

Result
Infinite card draw; Infinite draw triggers; Near-infinite ETB; Near-infinite LTB; Near-infinite death triggers; Near-infinite sacrifice triggers
Variations
Cheaper, tighter, alternate lines
The loop needs a non-Tentacle 1-toughness creature to start the chain; any cheap token producer like Anointed Procession accelerates Tentacle output but the combo doesn't need it to loop. Once the library is drawn, Laboratory Maniac or Jace, Wielder of Mysteries closes the game — the engine generates no direct damage on its own, so a win condition has to be in hand by the time the library empties.
