Clash Royale Legendary Arena Deck review and achievement

Well, Finally I have reached legendary arena for the third time in the row. I don't know how long I am going to retain this position but for me reaching this level without having a clan to work with is a big achievement. 
MY love for golem developed long back when I first started playing clash royale. I got this golem around level 7 I guess.
Since then my all decks revolve around this. if you ask me what is the mechanics behind this deck then I would say that it is low on defense but when it starts rolling there is no stopping. it. Especially when in double exilir time when you can land two extra pumps on a golem push. I have won matches where I have two golems on different rows of the tower and wich to support. Most of my matches start with losing tower It guesses it will be right to say that pump does have its drawbacks. As soon I land the pump people are generous enough stack the attack. But as the exilir builds up and golem starts rolling we end up giving them a hard time. Please do share your decks here too.
