I like what's been mentioned so far, I do have some thoughts / concerns, but in general seems like very solid work
Death: I think stall could be a good call, though it makes me a little sad if we discard all the thunderstorms. Still, good is good. I think stall over Air Domin tbh. I wish the air stall had more healing than just purify though, but nothing can be done about that, and Lightstall feels wrong unless we pack Dessication. But. What about AdrennaStaves/Puffers? Smashes through Bonewalls, healing to combat PDial type things, might stand to rush. AirStall could really work too, I'm just throwing ideas.
Fire: I do really like DryWall, will be interesting to see whether it can out-do Bolt OTK in a damage race with only 3 Bonewalls though. If we could make a tinkerer SpeedPoison with BoneWalls that INCLUDED some Dry Spell, rather than going full Dry Spell spam, i'd be happier. Keep some stall, and bonewalls, but have a little more damage potential (and things for them to waste Bolts on). Could be a tricky build though, and DryWall is still a good option.
Entropy: hehe... mono tears eh? Well, if it works, it works! What I love about it is that from previous wars they have tried to stall and tried to domin, NT should do a job against both. DBH would probably still give it problems, but overall I'm happy. i wonder about -1 bolt -1 shield +2 pillars though... I sense dead-draws with 3 Ice shields, and if we are gonna do a rush deck, may as well really go for it
Earth: Toadmare, yubyub. Combats fractal, steals Diamond Shields and Gravy Shields, can function ok against pulvy. I think we should use some ups in pillars though, because EQ split.
Time: Toughest one imo. I actually quite like Barebones Dials as an option, but if they use instosis again, that could be a huge problem. And I think they really might do instosis again.... But then they have a counter for pretty much everything we have, so we need to pick something.. One thing i would say is that nymphs really suffer against RT, so i'd avoid using them, pretty much at all.
