I did need the brimstones simply because I don't think the AI will cremate anything else in the deck. That was basically the only reason they were there. Also, I never put precognition into an arena deck unless it is 35 cards; since it can't gain any advantage from looking at the cards, the only reason to use it is to speed through a deck faster. If a human were to play this deck for some bizarre reason, then I would agree with you on that point. I don't think that the shard of patience conflicts with the idea at all, but pest and bravery do somewhat in the later game, since if you are denying the opponent the ability to play much and thus fill their hand up, then shard of bravery can't draw you very much, but it does certainly help in getting to that point in the first place. The pests are also something from the original version of the deck that I tried to make, which was an extremely weird rainbow, and the pests were a way to use both earth and darkness quanta, but it was trying to do way too much at once (stuff like bonewall/boneyard, ball lightnings, fractal, raging voodoo, and all at once... it was just too much to fit in)
