Biorhythm

[Mattao19]

I cast {Biorhythm} and neither me or my opponent have any creatures. What happens?

From Gatherer:
Rulings
10/4/2004   If a player controls no creatures when this resolves, their life total will become zero and he or she will lose the game.
10/4/2004   This spell causes the player to lose or gain enough life to change to the new life total.

I know but both players have 0 creatures

Then it's a draw

Wouldn't it be like the {deflecting Palm} deal where both players go to zero at the same time and the game ends in a draw?

Then it's a draw

Oops, take-back phase

[Mattao19]

Actually? Wowza ok thanks a lot!!

[mickeven]

Draw. Both players lose.

104.4a. If all the players remaining in a game lose simultaneously, the game is a draw.

And that's why it's banned in EDH
