Kuroaitou, I think your losses were caused by poorly designed decks or bad luck, rather than lack of skill. You're a pretty good time warrior and I really don't mind if you sub or anyone else.
Anyway, in case no one else can, you should sub because otherwise it's an autolose.
Thought the deck is an almost suicide deck, so unless
plays a suicide deck, or you have a really good draw (discord + enough pillars) it really doesn't matter who plays.
