How it works
Activate Collector's Vault by paying 2 and tapping it, causing you to loot and create a Food, a Clue and a Treasure artifact token.
Activate Clock of Omens by tapping two of the artifact tokens, untapping Collector's Vault.
Activate Krark-Clan Ironworks by sacrificing an artifact token, adding CC.
Repeat.
This looping engine turns a simple rummaging effect into an overwhelming surplus of resources by exploiting the incredible token-multiplying replacement effect of Academy Manufactor. When you activate Collector's Vault to draw and discard, Academy Manufactor replaces the single Treasure with a trio of a Clue, a Food, and a Treasure. You then leverage Clock of Omens by tapping two of those newly minted artifacts to untap Collector's Vault, while any excess tokens can be fed directly to Krark-Clan Ironworks to generate a steady stream of colorless mana to keep the entire loop going.
