In the early stages of deckbuilding for
in war, we tried to get a rainbow denial to include Gotp and nightmare and discord BH, It wasn't to successful because 1) the quanta generation was too slow and 2) the chances of those combos is small with so few copies of each card.
I think in the upgraded environment, you have solved problem #1, but problem #2 still exists.
IMO, you could probably do with 4 copies of GOTP 1 hourglass instead of 6 GOTP and -1 rewind and 2 more nightmare. It might up the chances of a successful denial while it limits your damage potential
