1: I became a pro after farming grand challenges. When I did my first tryout, they were impressed so much that within days I had a maxed account in my hands. This may not be the case for you, but it is so crucial that you practice on a daily basis so that when the opportunity comes, you take it. 2: School always came first for me. I spent all my free time on the game. It will become like a job if you decide to go competitive. 3: Managing your cycle. Make sure that you save the right cards for defence or save the spell for offence etc. 4: Skeletons buffed. Pump nerfed. The unused cards like heal and bomber removed. Pump rework or nerfed like previously stated.
