This deck is great, for me i was stuck at arena 4 and it brought me all the way to arena 6 it can counter anything if you use your elixir right.
The giant is used mostly for a tank to protect the bomber and wizard, but if you have both of them behind him then he should make it to the tower with most of his health left, and if he makes it to the tower with both of the bomber and the wizard behind him then the tower is pretty much yours.
The wizard is probably the most essential troop in this deck because he can target air and ground troops, a wizard right behind a giant is great because it can defend the giant from almost anything.
The bomber is good behind a giant, but be ready with your arrows just in case they place a minion horde. Also used to counter barbs and start a counter atack.
The skeleton army is good for defending against the p.e.k.k.a., giant skeleton, prince, golem (but they will die when it splits so be ready), and hog rider if you dont have a cannon in your hand, also could be used as a time waster in the final seconds to keep your tower safe.
The hog rider is good for quick pushes like if you need to get the last few hit points on a tower before the time is up works well with spear goblins. you can also place them in one of your pushes if your giant, bomber, and wizard has successfully defended against their atempt to defend tou can place a hog rider behind them to take the spot of the giant once it dies because the hog will run passed the bomber and wizard and become the tank while still doing a lot of damage.
The cannon is good for defending against the hog freeze combo, princes, and dark princes.
Arrows are good for defending against minion horde and spammers.
Spear goblins are good with hog riders (try to place them at the same time so they work together) they can also be used to help the giant, bomber, and wizard on their push.
Always place down your giant first at the back behind your king tower to save elixir for your bomber try to place your bomber down behind your giant first just in case they use a fireball on the bomber, if they dont then follow the bomber with a wizard so if they place dow barbs on your bomber your wizard will be able to take them out while your giant is getting hitpoints on their tower.
if you have placed down a giant on one side and they counter it with something that you couldnt avoid or couldnt defend the giant from then you can quickly place the hog rider and spear goblins down on the opposite side, and because they're low on elixir you are almost guaranteed hitpoints on that tower.
