Sindri, Nissa’s Protégé

Landfall- Whenever a land enters the battlefield under your control, you get {e}{e}.
Whenever you cast a creature spell, you may
pay X{e}. If you do, reduce the cost of that
spell by X.

Nissa visited Kaladesh many years ago, and
her influence can be seen in the wildest of Kaladeshi druids.
