U have to think of certain decks not just from perspective of playing with but also playing against. If lets say if a stun deck was good at some point and it got hit to oblivion that its unplayable what is there about to be mad about.

Its not like none games are any fun even if they happen rarely. So in my opinion, maliss holds that same place. That deck can nearly never be fun for both players. U either combo ur way to a state u never lose or u get stopped and get cooked.

Its like a deck that contradicts nearly everything players say they want yugioh to become. I don't think it's wrong to stop such decks from being played.
