Broken perpetual mechanics bug
I blocked all of my opponents creatures none of them had double strike or trample I still received lethal damage from a creature that had a perpetual +3/+3 it had no other abilities but because of how broken the perpetual mechanics are they cause errors like that. In the same game the same creature which was receiving -5/-5 from the Toxrill, the corrosive the creature only had a base P/T of 1/1 so that creature should have been dead a while before my opponent won. This game also had an incident where without any means to either damage or give one of my creatures lethal put said creature at -2/-2 below it's base P/T. My opponent didn't have any open mana or even the ability to trigger an ability to cause lethal damage or loss of power and toughness of the creature. Then later on they win without having any means of causing lethal damage. I am requesting a feature that would allow players to exclude arena only mechanics from play in all formats it would be best to have the ability to select which arena mechanics to exclude because the most common ones that cause problems or unfair play are perpetual or but just excluding all arena only mechanics would be fine.
