Toph, Hardheaded Teacher

Legendary Creature — Human Warrior Ally • Mana cost: {2}{R}{G} • Avatar: The Last Airbender • Rare

When Toph enters, you may discard a card. If you do, return target instant or sorcery card from your graveyard to your hand.
Whenever you cast a spell, earthbend 1. If that spell is a Lesson, put an additional +1/+1 counter on that land. (Target land you control becomes a 0/0 creature with haste that's still a land. Put a +1/+1 counter on it. When it dies or is exiled, return it to the battlefield tapped.)
