Rain of Riches - New Capenna Commander Promos

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.)
