Ben, Tempest Incarnate

Cascade

Whenever you cast a spell from exile, create a 3/1
red and blue Elemental creature token with haste
and “When this creature dies it deals 2 damage to
any target.”

{g}{u}{r}: Exile a card from your hand face down.
You may cast it on a later turn for its mana cost.
If a spell is cast this way it gains cascade.
