Sorcery — Lesson

Earthbend X, where X is the number of Forests you control. (Target land you control becomes a 0/0 creature with haste that's still a land. Put X +1/+1 counters on it. When it dies or is exiled, return it to the battlefield tapped.) Flashback {5}{G} (You may cast this card from your graveyard for its flashback cost. Then exile it.)

Niche combat trick for Gruul aggro and landfall strategies, but the high mana cost and dependence on controlling multiple Forests limits its practical impact in most competitive formats. Best suited to casual Commander decks built around land animation or +1/+1 counter synergies, where the flashback option provides some additional utility.
