You have some good units. I would focus on leveling up Elza, Luther, Douglas, and Tridon. I too am F2P and after about 9 months am at summoner level 141, unit capacity 210, 26 six-star units. My advice is to never use gems to restore energy or to continue after a game over. Save them for rare summons and expanding unit or item capacity. When you do use gems for rare summons, wait for an event with higher chance for units you want. Don't bother with BB leveling until a unit is at 6*. Use fodder units (burny, goblin, etc) until you get to at least BB7, and save the burst frogs until after that. Use fodder units again to level SBB. Save your imps for units which you know you will use most often. And be especially thoughtful about who you use sphere frogs on, as they are so rare. Most important is to be patient and enjoy the process!
