Treefolk Storytellers

Whenever Treefolk Storytellers or another Treefolk creature enters the battlefield
under your control, you may return target historic card from your graveyard to your
hand. (Artifacts, legendaries, and Sagas are historic.)
If history were taught by good storytellers, it
would be never forgotten.
