Cascade
Spells with Arc Affinity, Solar Affinity, or Void Affinity you cast have cascade.
Whenever a creature you control deals combat
damage, shuffle target nonland permanent you
control into your library and exile cards from the top of your library until you exile a nonland permanent, you may cast that spell without paying its mana cost, then put the rest of the cards onto the bottom library in a random order.
