Whenever you cast a noncreature spell, create a 0/1 blue Homunculus creature token.

Sacrifice Homunculi tokens:

1 Homunculus — Draw a card, then discard a card.
3 Homunculi — Until end of turn target noncreature card in your graveyard gains flashback. The flashback cost is equal to that card's mana cost.
5 Homunculi — The next noncreature spell you cast this turn gains cascade.

“Kblthd, go fetch.”
