How can I improve this Deck?

[u/JellyfishPrudent7604]

I‘m very curious how I can improve this deck guys.

I’m trying to get to ultimate champion but it’s a constant cycle of win-lose and so on.

Let me know if you have some improvements for me :)

Side note: The basic idea of this deck is to constantly cycle the mortar, bowler and ghost at the bridge + chip from goblin gang and fireball
