I just want to share the deck that I use from arena 6-7. I am currently sitting at 2290 cups and decided to share my deck. This deck is good against almost all the decks out there, I would say I have 70-75% win rate with this deck.
How to Play:
If your starting 4 cards have golem in it. You should wait to 10 elix (or the elix bar is at 9.5 so you could compensate with the delay) before dropping it. ALWAYS I say ALWAYS put the golem behind the tower if you are not yet in under 60 sec. Because if you drop golem quite advance you wont be able to drop supporting troops or defend the other side of the map quite effectively. Personally I always try to put wizard behind the golem most of the time those 2 rekt the other side, but sometimes good players tend to surround it with barb or some cheap troops when the Wizard is locked in a target. But that is also okay coz the golem can pretty much dish out a lot of damage to the tower. also if you have enough elix you can put poison in the tower so the golem will last longer and try to follow up hogs (but most of the time this only happens when x2 elix)
