Maelstrom of Possibilities

Cascade (When you cast this 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.)
Storm (When you cast this spell, copy it for each spell
cast before it this turn. You may choose new targets
for the copies.)
"From chaos can spawn anything."
