Create A Good Deck
Your deck must comprise card attacking ground and air both. You must take something for defense eg. Bomb tower, cannon or inferno tower. Your deck must be a balance one with defensive and attacking troop like musketeer for air troop and barbarian for ground one.
Use combinations of troop
Your deck must have cards that you can use to make a powerful combination. There is a list of some powerful combinations :
1. hog rider + freeze
2. hog rider + goblins
3. hog rider + fire spirits + zap (I personally use this combo)
4. hog rider + zap
5. hog rider + fireball
6. giant + archers
7. giant + wizard
8. giant + witch
9. giant skeleton + wizard
10. golem + wizard + valkyrie
11. prince + valkyrie
12. prince + dark prince
There are lots of combinations that you can use to win easily
Using elixir efficiently is the key to victory
You have to use elixir very carefully. If you are out of elixir then your opponent can take your tower easily. So you have to be careful and attack while your opponent is out of elixir or have less elixir. You can use elixir collector if you have.
Practice makes man perfect
You have to practice with your deck constantly without changing it. When you find your perfect deck start practicing with it. you may loose some battles but it will help you later. so start practicing from now.
