It essentially would make that person impossible to damage other than unavoidable damage if the infinite loop is possible for the entire round until it is their turn again
With a small enough deck that combo could be possible with a bit of luck potentially every other turn making them not be able to be attacked every 2nd round they take a turn
I assumed by the wording different creature it meant a creature that isn’t named Ballz Brothers but now am not sure so would like a developer to clarify it for me thanks
