I hope to get some fixes xD

pretty solid build, you can try these fixs though and see if they work.

-1 airbellum
+1 chariot
you have enough targets for rescue cat, and chariot is one of the best cards in the game right now, wrecking every major deck (even skill drain variants since it can negate recruiters)

-1 vortex(side for ls)
+1 shrink
shrink lets you tag (leading into a gyzarus play) and the only big swarm decks right now are blackwings and lightsworn, which you can side this for.

now, im not sure about those fixs, see how they work for you.

hmm...I've got a few more changes to make. With Proving Grounds around, you don't need many copies of most GB. Only 1 copy will suffice for all except the most necessary ones, and you're missing Equeste!!! He's what will keep your card advantage alive!

-1 Airbellum
-1 Hoplomus
-1 Darius
-1 Smashing Ground
-1 Vortex
-1 Brain Control

+2 Equeste
+1 Proving Grounds (this should always be maxed!)
+1 War Chariot
+2 Solemn Judgment

oh good catch neko, i didnt notice he had no equests lol. but equeste is actually fine at 1, id run the smashing over the second copy.
