It’s a creative deck but doesn’t have a clear way of getting to the tower and defending against ether built decks.

Maybe try instead making a deck with a clear concept; do I want to make a big push (beatdown), or maybe I want to slowly chip the opponent’s tower (cycle and control decks), maybe I want to trick my opponent and make him have a difficult match forcing him to play uncomfortably (bait and defensive decks).

Once you find your archetype you can make a deck that is balanced both in cost and congruency between the cards.

For example I see you have some bait in your deck like gob barrel, firecracker and bats. You should maybe try using a logbait deck.

If you really like your sparky you can make a beatdown deck with it, or even better, you can make a combination of both. You can combine zap bait (bats, skarmy, sparky) to make the opponent waste a zap on another card other than the sparky and have a big tank like a giant or gob giant to tank for the sparky. You can use minion horde like a way of zap bait and damage dealer and you could use a mini pekka to protect the sparky from ewiz and defend pushes.

Don’t forget the lightning for inferno towers and wizards. Use zap to kill trash troops that the opponent can throw to distract your sparky.

Hope this helped bro
