[Ask] Need some help in arena 6

Hi! I started playing this game less than a week ago, I'm level 5 and in arena 6, and I've come to the conclusion that 1700 trophies is the best I can manage.

1. No matter how much I grind, i can't get rid of the chests, so playing more doesn't give me anything. If playing games gave xp, I could play more game and get better towers, allowing me to somewhat outweight the lvl difference, but it doesn't. At this point, it feels like the game is simply about waiting 3h, opening a chest, waiting 3h, opening a chest, waiting 3h, opening a chest, waiting 3h, opening a chest, playing 8 games to gain 4 chest, and do it again.

2. I don't have any legendary, I don't have the prince, the witch, the skeleton army, the giant skeleton, or the minion horde.

3. 3/4 game I play are against people where my lvl 5 arrow isn't enough to kill their horde, resulting with me insta-losing the match. (any push is countered by horde fairly easily at this point). Furthermore, while prince alone is somewhat countered by [P.E.K.K.A, inferno tower + skeleton, or a well placed tombstone], prince + aoe is very hard to counter (or so i think) without expanding a lot of ressources. Same goes for horde/skeleton army : every deck i go against has these cards, and if I don't have my arrows when they drop, there's little I can do to prevent them from swarming my towers / destroying my pushes.

Here's my deck :

• Musketeer lvl 4 for anti-baloon mostly, as well as some anti-baby dragon.
• P.E.K.K.A lvl 1 to gain massive advantage against prince when I have enough energy, as well as pushing power with arrow.
• Baby dragon lvl 2 cause it's op. Anti-horde as well.
• Arrows lvl 5 to counter horde (sometimes...), and skeleton army while pushing/defending.
• X-bow lvl 2 to finish a starved opponent after his prince drop, helps defending after getting first tower as well.
• Balloon lvl 2 as my main counterattack.
• Inferno tower lvl 4 against big minions and to defend towers along with x-bow.
• Tombstone lvl 3 as bait for balloon, defence against mini P.E.K.K.A, P.E.K.K.A, kills prince when under tower, pressure, so on.

Main push is P.E.K.K.A+Balloon followed by arrows, or X-bow+musketeer followed by arrows

Available cards : Skeletons, goblins, spear goblins, fire spirit, zap, knight, archers, minions, bomber, cannon, tesla, barbarians, valyrie, mini P.E.K.K.A, hog rider, furnace, fireball, giant, wizard, gobelin hut, bomb tower, rocket, goblin barrel, lightening.

Am I doing things wrong? Is there a way I could make my deck better? Is there a way to progress beside waiting for chest every 3 hours?

Cheers, and have a nice day.
