He was faster and you don't have much defense ? Look for beginer video on youtube to learn about the game. You have a lot to learn.

They have slightly more power than you. Also your 6* Ezio is level 1 while their 5* Ezio is level 50. It has better stats since it is max level for its ranking. Yours is level 1 and needs to level up to get its stats back.

I think that his ezio was just faster. if you're was hitting first would have been your win
