[Ask] What can i do to improve this deck? A4-5

deck: http://imgur.com/a/v8ClM

i keep getting 1* every match (50% of the game), and the rest draw with this deck. im not lucky with the chest drop (only 1 magical chest at a2 and 1 giant chest a3)

not getting enough wizard to use at a5, i lost pretty much i drop down to a4 again. no luck with freeze / goblin barrel either, the shop keeps selling the one i dont need

the amount of games i need to open crown chest is so many, getting +1 is hard, and many of draw games, not mentioning i keep getting matched with high level people (lv 7 with lv3 baby dragon as example) is very demoralizing

i already read the season 3 meta breakdown decks, but i dont have access to luxury card such as princess / goblin barrel. the only deck i can use is the spawning city, but i dont feel like it
