The other day I was playing a janky Pendulum deck that turbo's out DDD Supreme King Kaiser to OTK. It is in no way meta or unfair as you can tell, just a casual deck for fun at locals. First match I face a Phantom Knight player and manage to FTK with Supreme King Kaiser because they weren't familiar with how it stuns the board and can attack three times. Same thing happens the next turn. I can see why someone would be upset at losing so quickly to a random deck, but they started ranting about how unfair the deck is and how unfair it is to face a meta deck when they're playing casually. For sure I can see being mad if you want a casual gale and end up facing Sky Strikers or Rhongo Bongo, but it isn't my fault if your casual deck can't beat other casual decks.
