I used this deck to climb from rank 20 to 3 with an 31:13 record and also played it in the invitanional tournament, but I only went 8:7 there. It is basically your basic dragon midrange deck, just equiped to deal with the new meta (but be aware that the meta is still kind of unclear, so try to keep up with changes by updating the deck if necessary).
The early game mostly consists of card draw and small removal.
Blightmoth is just a good all around card that kills a lot of small stuff (and effectively voidbounds them), can be sacrificed for Display and plays around Vox (even though Vox sees less play right now).
Defile is really good right now, it kills everything in FTS Jekkinations and FTP token decks while also denying them the unit for machinations (and if you Defile a Jekk on its summon they wont draw a Treasure Trove).
Display of Menace is good just for its flexibility, I used all 3 modes several times. The sacrifice allows you to effectively dodge removal, the relic removal is self explanatory and the small AOE can be good against some FTS/FTP/Praxis starts.
Turn to Seed and
Cremate are good against slower decks, but they are also effective against FTS and FTP.
The dragon lineup consists of 4 Eclipse Dragons and a lot of more specifically tailored dragons that can be fetched with
Dragon Forge if necessary. The
Eclipse Dragon are just all around good and cost effectively 2 mana most of the times.
Karvet, Redeemed can fix influence and has good stats,
Skylord Tolek can provide lethal with some dragons on board,
Karvet, Solar Dragon can provide some chump blockers and lifegain,
Spitflame Draconus is spot removal on legs,
Noxious Wyvarch clears the board against FTS /FTP etc. and
Stonesmelt Dragon is even more relic hate.
The market is pretty standard, the only notable exlusion is
Eremot's Designs because the deck already has enough ways to clear smaller boards and Designs cant do anything about void recursion.
Edict of Linrei is better at that, because it not just effectively kills the unit but also transforms it.
Provoke the Dragons can kill smaller units and provide lethal with a few dragons.
Unseal is self explanatory with 4 Eclipse dragons in the deck and
Voprex's Choice is good against slower decks.
Like you probably already recognised, a lot of card choices are tutored towards FTS/FTP(S), because they are probably the best decks right now and they would be really hard to beat without that much hate. I still have to admit that the matchup is difficult and that you really have to think about every decision. All other matchups feel beatable right now,
Icaria, First Reaper can be though, but if you keep a Turn to seed for here its usually fine.
Good luck and have fun!
