Rainbow Cascade

Search your library for up to one card with mana
value X or less and exile it, where X is the
number of dream counters you have, then
shuffle. You may copy the exiled card. You may
choose new targets for the copy. You get a dream counter.
Epic (For the rest of the game, you can't cast spells.
At the beginning of each of your upkeeps, copy this
spell except for its epic ability. You may choose new
targets for the copy.)
