Increasing Bewilderment

Each player discards his or her hand, loses life equal to the number of cards discarded this way, then draws cards equal to the life lost this way. If Increasing Bewiderment was cast from a graveyard, each player loses twice that much life instead.
Flashback {4}{u}{b} (You may cast this card from your graveyard for its flashback cost. Then exile it.)
I..., wait what?
