Hi! Sorry for the slight necro, but I'm doing this for Phase 1 of the Death Trials. This deck is definitely a unique concept, one that I haven't seen before. I think Manuel brought up a few good points, especially about early in the game. It seems that this deck would take several turns to set up in order to pull off the dry spell combo, and chaining Bonewalls isn't necessarily going to hold off an initial onslaught given the fact that you only have 4 in the deck. Because of that, I would probably include a few CC cards at the expense of a few dragons. 8 total dragons is a little bit excessive, especially considering that in an ideal situation you'll already be nearly halfway through the deck before you can pull off the combo successfully, and that you won't need to rush to the finish if you build up a large collection of Bonewalls. So I would suggest cutting 2 Arctic Dragons and 1 Ivory Dragon, and replacing those with a combination of freeze and ice bolts. Ice bolts can also serve as damage replacements at the end of the game after racking up lots of
quanta if you need a little more damage to push you over the edge for the win. An Arctic Squid could also be used there if you want to have consistent CC. I would also agree with Manuel that you'll be a bit quanta starved towards the beginning of the game, which makes chaining and setting up the combo a bit difficult, so I would swap another Ivory Dragon out for an addition Bone Tower. This would give you a final deck that could look something like this:

Other tweaks could include having SoSac to stall or having an Arsenic to ramp damage while you wait for the combo to build up. Other than that, I really like this idea, and it seems like a lot of fun to play with. Good job!
