Avenging Druid + Retreat to Coralhelm + Psionic Gift

Avenging Druid

Retreat to Coralhelm

Psionic Gift

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.

By enchanting Avenging Druid with Psionic Gift, we grant the Druid the ranged firepower it needs to trigger its own ability directly. Every time you tap the Druid to ping an opponent, its combat-style damage trigger fires off to reveal cards until you hit a land, dumping everything else straight into your graveyard. The moment that land enters the battlefield, Retreat to Coralhelm triggers its landfall ability to untap the Druid, looping the whole process to empty your library and put every single land you own onto the battlefield.
