Avenging Druid + Retreat to Coralhelm + Power of Fire

Avenging Druid

Retreat to Coralhelm

Power of Fire

How it works

1. Activate Avenging Druid by tapping it, dealing 1 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 delightful brew turns Avenging Druid into a self-mill and land-ramping engine by granting it the tap ability of Power of Fire. Each time you ping an opponent, the Druid's damage trigger flips cards from your library until you hit a land, dropping it straight onto the battlefield. That newly entered land immediately activates Retreat to Coralhelm, whose landfall trigger untaps your enchanted creature and lets you repeat the whole process until your library is completely emptied of lands.
