Verdant Succession + Elvish Soultiller + Ashnod's Altar

Verdant Succession

Elvish Soultiller

Ashnod's Altar

How it works

1. Activate Ashnod's Altar by sacrificing Elvish Soultiller, adding CC.
2. Elvish Soultiller dies, triggering itself and Verdant Succession.
3. Resolve the Elvish Soultiller trigger, shuffling all Elves or Mutants from your graveyard into your library.
4. Resolve the Verdant Succession trigger, searching your library for Elvish Soultiller, putting it onto the battlefield and shuffling your library.
5. Repeat.
