How do you deal with giant?

Ok i got attacked a lot by pro high level player(i'm level 32, the raider level 49+). They mostly use high leveled giant (Their HP is too much). I'm so desperate with this, especially the giant + healer + wall breaker combo.

Btw, my defense is :
-pocketed base (i thought this is effective against giant @_@)
-level 5 walls
-2 mortar level 3
-4 cannon level 7
-3 archer tower level 6
-2 wizard tower level 2

And so i thought i have a decent defense, but i never succesfully defend against giant attack.

So, how do you guys deal with this tanky gigantism @_@?

Upgrade your defences and they'll soon be able to take out giants. Splash damage aren't really the key component to killing them, it's more high leveled cannons and archer towers. I use funnel walls with spring traps to help take them out too.

actually wizards are far more effective on giants. Also if you get attacked by healers place your air defences in a good place and upgrade them too
