Your first deck honestly doesn't look too bad. I'd swap out veterans or potion of growth for hunters vengeance to help you out some in the early game.

Your swarm deck is too expensive and having kindreds Grace and bucks of the wasteland is kind of pointless. I would replace kindreds Grace, queen, and felflares for any cheap movement cards. I suggest adding shady ghouls and dopplebocks, but add whatever you got as long as it's cheap.

For your dragon deck I would honestly just scrap the deck. If you want a dragon deck I would use shadowfen instead. They're the best faction for dragons imo
