Thunderous Conclusions

Look at the top five cards of your library. Until
the end of turn, you may cast a instant or sorcery
card from among them. Put the rest on the
bottom of your library in a random order. If the
card casted has mana coast 3 or less, copy that
spell, you may select new targets for the copy.
-I've seen your future, it's full of
thunder, burns and defeat.
