Warp Lightning Vortex

Each opponent reveals cards from the top of their library until he or she reveals a non-land card.
Warp Lightning Vortex deals damage to that
player equal to that card's converted mana cost.
Then that player puts the revealed cards at the
bottom of his or her library in any order.
Coruscating bolts of warp lightning leap out from the vortex, obliterating those nearby.
