How it works
During an opponent's turn, activate Grand Architect by tapping a blue creature you control except Unctus, adding CC that can only be spent to cast artifact spells or to activate abilities of artifacts.
The creature triggers, causing you to loot.
The Watcher's first ability triggers, creating a 1/1 Tentacle creature token.
