Hardened Tactician + The Watcher in the Water + Pitiless Plunderer

Hardened Tactician

The Watcher in the Water

Pitiless Plunderer

How it works

1. Activate Hardened Tactician by paying 1 and sacrificing a token.
2. If you sacrificed a creature token, Pitiless Plunderer triggers, and The Watcher's second ability triggers if the creature token was a Tentacle.
3. Resolve the Pitiless Plunderer trigger, if applicable, creating a Treasure token.
4. Resolve the Watcher trigger, if applicable, untapping a Kraken and putting a stun counter on up to one nonland permanent.
5. Resolve the Hardened Tactician ability, causing you to draw a card.
6. The Watcher's first ability triggers, creating a 1/1 Tentacle creature token.
7. If you control a Treasure, activate it by tapping and sacrificing it, adding 1.
8. Repeat.
