The Watcher in the Water + Symmetry Matrix + Thermopod

The Watcher in the Water

Symmetry Matrix

Thermopod

How it works

1. Draw a card during an opponent's turn.
2. The Watcher's first ability riggers, creating a 1/1 Tentacle creature token.
3. When the Tentacle enters the battlefield, Symmetry Matrix triggers.
4. Holding priority, activate Thermopod's second ability by sacrificing the Tentacle, adding .
5. When the Tentacle dies, The Watcher's second ability triggers, untapping up to one Kraken you control.
6. Resolve the Symmetry Matrix trigger, causing you to pay 1 to draw a card.
7. Repeat from step 2.

This intricate loop turns instant-speed card draw during an opponent's turn into a self-sustaining engine, anchored by The Watcher in the Water spitting out a Tentacle token every time you draw. Symmetry Matrix eagerly watches these tokens enter the battlefield with equal power and toughness, letting you pay a mana to draw a card that restarts the entire cycle. Meanwhile, Thermopod provides the necessary sacrifice outlet to convert each Tentacle into red mana while also triggering The Watcher in the Water's second ability to untap your Krakens and keep the board state locked down.
