On multiple effects per turn there should be an option for both parties to agree to a skip of the automatic loop the logic is in.

Once they both agree the effects are applied. If the effects extend to the third warning both parties are given the option to skip the loop. If not then the match will result in a loss to the one that refuses, or a draw otherwise.

Had 500+ health and used x/x tokens per life. Then had get +1/+1 per creature enter the battle field. Then I had +1 life per creature enter the battle field. Then I had +1/+1 per life gained.

So the game resulted in a draw, sometimes a guy just wants to bully the AI when he can.
