how many freezes do we have? I was thinking of a deck like this: Deck inspired by Jmdt's ice drags deck.
5f0 5f0 5f0 5f0 5f0 5f0 5f0 5f0 5f0 5f0 5f0 5f0 5f0 5f0 5f4 5f4 5f4 5f4 5f4 5f4 5fc 5fc 5fc 5fc 5fc 5i7 5i7 5i7 5i7 5i7
Since gravity creatures are mostly based on skills, then we might as freeze all of them before they activate anything. Phoenixes to just deal some damage and since theres so much quanta production, then we might as well pack some bolts to finish off the opponent. Offering us 2 strategies, so even on the second match the opponent will be a bit undecisive on his tactics. I could have +1 freeze -1 pillar/firebolt. I could also switch freezes to rage pots. PC won't be necessary since phoenixes will get through grav shields, titans would be a little bit of damage but I think this deck can outrush it with a good deck. Phoenixes in case of too many otys or BB/grav shield combo. Drags would be limited damage.
Jmdt's deck: I just tested it a few times, your deck seems a bit low on quanta production. I also think it bases it's tactics on getting the right cards in the right time. I got only 1 pend this one time, then got crushed by AI3, lol.
EDIT:
I found phoenix takes a lot of quanta for fire bolt decks to work, so I could just as well make it creatureless:
5f0 5f0 5f0 5f0 5f0 5f0 5f0 5f0 5f0 5f0 5f0 5f0 5f0 5f0 5f0 5f0 5f4 5f4 5f4 5f4 5f4 5f4 5f7 5f7 5f7 5i7 5i7 5i7 5i7 5i7
3 fahrenheits to increase chance of early draw. I hope we have 5 freezes, so the deck will be as stall-typed as possible. I doubt this deck will give anything away about our vault. Also, I played a creature-only deck, if I play a fire bolt deck right now, It'll be harder to predict what deck I'll use next. I just tested this fire bolt deck against AI3, it won even against that annoying fire/death/darkness trio, it deflagged 2 of my fahrenheits but I got my third one when I got like 70 fire quanta so... Went 10-0
Most decks will only pack 2-3 deflags/steals for backup PC and I doubt that they'll get all 3 in the first 7 turns.
