I see quite nice cards you have. Since you are motivated, try to figure out why you lost a game. Analyzing after the game, how to change your team of a lost game could give you some new ideas. IMO if you manage to be focused all the time on battle rule sets and position of your monsters in team, then you could see a bit of a progress.
Thanks, I have been testing out new cards and methods, its a fun game! Enjoying it :)
