Sola, Arcane Insurgent

Sola, Arcane Insurgent gets +1/+1 for each
instant and sorcery you own in exile.
Whenever you cast an instant or sorcery card,
exile it. Then chose a card exiled with Sola,
Arcane Insurgent at random. You may copy that
card. If you do, you may cast the copy without
paying its mana cost.
When everything is still, the only way to break the
silence is chaos.
