Hi guys! We must also play this game and this is one from our decks! We get to Arena 7 with this deck!
Giant works as tank. You can put Wizard or Bomber behind him.
With Musketeer or Wizard you can get air targets easily. I get Lava Hound quick with Fireball help.
Mini P.E.K.K.A. is great to get down tanks like Giant, Giant Skeleton, Hog, Golem or others.
Spear Goblins are good to help deck rotate.
Barbarians can get to Towers with backup.
Bomber can get hordes.
