[Ask] Need help refining a deck.

This is the deck:

Elite Barbs (lvl 5 soon to be 6)

Dark prince (lvl1)

Fire spirits (lvl7)

Wizard (lvl4)

Fireball (lvl4)

zap (lvl 7)

musketeer (lvl 4)

minions (lvl7)

The main win condition is a combo with the barbs and dark prince, trying to catch the enemy off guard elixir wise. However, my other choices are not doing a good job of getting positive elixir trades (zap is tho). What substitutions should I make to strengthen the deck, or was it doomed from the start?
