Death Showdown

Target creature you control fights another target
creature.
Shuffle an event named Colosseum in your
library that reveals players hands and exiles all
instant and sorcery spells revealed this way.
Each player draws cards equal to the spells
exiled this way. Creatures get +3/-1 for the rest
of the game.
(Whenerver an event is put into a player's hand it is
casted and exiled, then that player draws a card.)
