Ever attacked someone and know you can win him easily? Take a lookout for him when its near 9pm and secure your placing. [Knowledge 1]
For gameplay part, there is just 10000000000000 things that I can write about because there are too many permutation of things that can happen. I will attempt to teach and explain some good combinations and hero usage
Standard arena team
Leo - Jugo - Lumina - Bomo - Noire
Triple aura, big DPS and control from bomo which make this team very hard to beat. However it will pale after lv 73 as physical team will lose effectiveness due to increasing heroes gaining dodge [Knowledge 2]. People normally swap lumina for hydral / booster after lv 73 for more control.
