Avenging Druid + Retreat to Coralhelm + Heavy Arbalest

Avenging Druid

Retreat to Coralhelm

Heavy Arbalest

How it works

1. Activate Avenging Druid by tapping it, dealing 2 damage to an opponent.
2. Avenging Druid triggers, causing you to reveal a land card from your library and put it onto the battlefield, and put all other cards revealed this way into your graveyard.
3. When the land enters the battlefield, Retreat to Coralhelm triggers, untapping Avenging Druid.
4. Repeat until no lands remain in your library and/or your library is empty.

This engine transforms your archer's toolkit into a relentless self-milling machine by weaponizing Avenging Druid with Heavy Arbalest, allowing it to tap and deal direct damage to an opponent while bypassing its normal lack of untapping. That damage triggers Avenging Druid's ability to dig through your library for a land to put directly onto the battlefield, dumping the rest of your library into your graveyard in the process. The moment that new land enters the battlefield, Retreat to Coralhelm triggers its landfall ability to untap Avenging Druid, priming the archer to fire again and repeat the entire loop until your library is completely emptied.
