Hey Sheriff, personally from my experience, I had a 18 bird and levelled it to 22 and had a LOT of fun! It was definitely a lot better imo! I would recommend levelling your bird to 20 since you might find more games. I would also recommend lvl15 bear. 15 bear is my absolute favourite pick above everything else Pocket Legends has to offer! You should also try 20/22 bear. Good luck and have fun :P
