Hullbreacher + Otherworld Atlas + Clock of Omens

Hullbreacher

Otherworld Atlas

Clock of Omens

How it works

1. Activate Otherworld Atlas' second ability by tapping it, causing you to draw a card for each charge counter on it and create that many Treasure artifact tokens for each opponent you have.
2. Activate Clock of Omens by tapping two Treasures, untapping Otherworld Atlas.
3. Repeat.

This brilliant legacy, oathbreaker, and vintage loop centers around Otherworld Atlas to force a massive draw step for everyone, which Hullbreacher instantly weaponizes by turning every opponent's extra card draws into a horde of Treasure tokens. Once you have enough artifacts lying around, Clock of Omens steps in to tap two of those newly minted Treasures and untap Otherworld Atlas, resetting the whole engine. By repeating this loop, you generate near-infinite colored mana and Treasure tokens alongside infinite card draw, drowning your opponents in their own card disadvantage while you reap all the rewards.
