Haze Of Begginings

You take an extra turn after this one, choose an opponent.
During the extra turn the chosen player untaps
permanents during your untap phase as if it was
their untap phase, draws cards during your draw
phase as if it was their draw phase, may have their
creatures attack as if it was their combat phase
during your combat phase, but cannot block your
creatures and you cannot block theirs; and both of
you may cast spells that turn as if they had Flash.
