Battle deck:
Replaceable cards: Musketeer can replace Baby Dragon; Poison = Fireball
Some tips:
1.
Main strategy: defense, take advantage of the elixir, fightback.
2.
Mulligan: when starting, try to see what your opponent plays first. If your opponent doesn't play anything, then put the cannon on board. Pay attention to what core troops and spells your opponent has in his deck. Don't play buildings at the early stage because sometimes, you play Barbarian Hut in one lane, your opponent will organize a wave of attack in another lane. You might lose a defense tower just by doing that.
3.
When to place the buildings: see what sudden attack cards your opponent has, like Prince or Hog Rider. If you are positive that you can deal with them, place the buildings.
4.
Where to place the buildings: if you have cannon in hand, it's better to place buildings behind the tower; if you don't, place the buildings in front of the King tower so it can attract Hog Rider or Balloon.
5.
Place Barbarian Hut or Goblin Hut? The answer is Goblin Hut first and then Barbarian Hut. The 4 Elixir Goblin Hut is better to place in the early stage because Barbarian Hut will cost you 7 Elixir, which is pretty high. Place it when you've already gained some advantages over the battle.
6.
How to play Giant Skeleton: normally speaking, Giant Skeleton is not used to attack but more as a defense unit, unless you are already sure that your opponent doesn't have enough Elixir to defend. Place the Giant Skeleton when your opponent plays a lot of small troops on board because they will all gone after the bomb. After all, play Baby Dragon + Spear Goblin to have a fightback or you can just place buildings.
7.
How to deal with Hog Rider or Balloon: don't panic when a Hog Rider is coming. Normally speaking, you'll have a cannon in hand. Even if you don't, our buildings can also attract Hog Rider's attention. Calmly play cannon in the right place and place Baby Dragon or Spear Gobins around Hog Rider. Noted that your opponent may play Freeze along with the Hog, so pay attention to the placement of Baby Dragon or Spear Gobins to avoid them affected by the Freeze.
8.
How to play with Prince/Pekka deck: use Spear Gobins to attract them or play Giant Skeleton. If your opponent has a group of troops incoming, don't hesitate to place Giant Skeleton.
9.
How to play with buildings deck: oh, try to draw with your opponent. Whoever has posion, he gains advantages.
