No, I think that deck will fail pretty hard against fire. I'm expecting them to use firestall, because honestly, I don't think we can beat it. I think that our best hope against fire is the fractal charger lightning deck. If they play one of those immorushes, the lightnings can hopefully buy some time. If they play firestall, we've got a lot of chargers that hopefully make a kill before we get bolted/fahrenheited to death. Due to deflags, I think our pulvy-based deck will fail, and firestall will crush DBH, as would immorush, another strong possibility (they lost with it twice last round, but should be able to put one together still). They could also do that fire/RT rush, their steam machine duo, or a fractal phoenix deck.
It is true that DBH could probably manage alright against those, but I'm pretty worried about firestall, and if I were rootranger, I'd probably send it against us, unless they need it more somewhere else. Also, scibra has 3 more upgrades, so I would do the three mercenaries (4/7 doesn't die to rage pot/elixir and needs a bigger firebolt, both of which are quite significant vs fire) and I'd do a pendulum after that, and probably unup a discord and up a 2nd pendulum. I also think that this deck is way too quanta starved for gravity. I'd replace 6-8 pendulums with pillars, and possibly even drop a card somewhere for one more quanta. You do -not- want to be stuck waiting 3-4 turns to play an otyugh, for instance, and other than discords, there's just the two dragons, and I don't think we need any more than 6 pends for all the entropy cards. Honestly, it really depends what you guys think fire will bring. That DBH will go 0-3 against firestall, and might struggle vs immorush unless it gets otyugh early, but it will rape fractal phoenix and probably excel against the time or water duos. I will be satisfied enough bringing DBH vs fire if we make the changes I suggested. It might be better to bring DBH and hope fire brings a deck that we should be able to win, rather than bring fractal chargers that they might counter, since they know it's one of our top decks. (though they know we've got DBH, too)
