Collector's Vault + Clock of Omens + Krark-Clan Ironworks + Primal Vigor

Collector's Vault

Clock of Omens

Krark-Clan Ironworks

Primal Vigor

How it works

1. Activate Collector's Vault by paying 2 and tapping it, causing you to loot and create two Treasure artifact tokens.
2. Activate Clock of Omens by tapping the Treasures, untapping Collector's Vault.
3. Activate Krark-Clan Ironworks by sacrificing a Treasure, adding CC.
4. Repeat.

This ingenious engine begins by activating Collector's Vault to filter your hand while generating a pair of Treasure tokens, thanks to Primal Vigor doubling every token created. From there, Clock of Omens harnesses those very Treasures by tapping them to untap the Vault, while Krark-Clan Ironworks can sacrifice any leftover artifacts to fund your continuous activations with surplus colorless mana. By cycling these pieces together, you can dig endlessly through your deck while generating an overwhelming mass of resources.
