P.E.K.K.A supercharge

Max out Pekka as soon as possible.
Get Lumberjack to 2* skipping the first upgrade.
If the pekka is dying to quickly place the healing ranger and give her unstoppable upgrade.
If the opponent has witch or any long range troops that is causing your pekka trouble then place fisherman to hook the it.
If the opponent has natureborn then place wizard and get the healing upgrade. Additionally wizard is good to counter witch.

This deck is based around making pekka extremely powerful. BK gives pekka extra damage, which makes pekka do 40 damage if you have 3 star pekka. Lumber jack can make pekka extremely fast. if you purposefully position your Lumber so that it is effected by clash abilities like prince and spear goblin. The pekka will almost always be immune to stuns as the healing ranger grants unstoppable. Fisherman can hook the entire enemy back line so and even stun it, this gives you a massive window to eliminate the entire enemy team. You mostly want to place Fisherman last, with the exception of wizard if there is nothing for wizard to counter.
