Rain of Riches

When Rain of Riches enters, create two Treasure tokens.
The first spell you cast each turn that mana from a Treasure was spent to cast has cascade. (When you cast the spell, exile cards from the top of your library until you exile a nonland card that costs less. You may cast it without paying its mana cost. Put the exiled cards on the bottom in a random order.)

Quand la Pluie de richesses arrive sur le champ de bataille, créez deux jetons Trésor.
Les jetons sont incités pour le reste de la partie.
