Firstly, I would like to inform you that, select a good deck. It should not be very expensive and not too cheap. Beacuse if you use expensive cards, it will take a lot of time to make elixir for it and if you use cheap deck then the troops can be killed easily by arrows. Again dont select all epic or epic and legendary cards only, because epic or legendary doesnt means the best. Keep some common cards like arrows,barbarians or spear goblins. And also some rare like hog rider,inferno,mini PEKKA or 3 muskeeters. It will be better if you keep some high damaging troops like balloon, prince or dark prince. And also keep the giant skeleton, beacuse its death damage is too high. And dont forget to keep ice wizard or princess. And also take at least 2 spells.

Thank you and clash on.
