Storm, Elegant Tempest

X-Gene — If this spell was cast for its X-Gene
cost, look at the top four cards of your library.
You may reveal an instant or sorcery from among
them and put it into your hand. Put the rest into
your graveyard.
Flying, conduit
Inspired — Whenever Storm becomes untapped,
you may pay {w}{u}{r}. If you do, exile target instant
or sorcery card from your graveyard. Storm deals
X damage to target creature or planeswalker
where X is the exiled spells' mana value.
