Current Raid Tournament

How is it that Vivica can be a tank on a team you are fighting and I have 2 purple heroes with 4 star Troops do little to no damage on her? Did I miss that teams have added strength or protection? Does this Raid Tournament of having Very Fast power up only for the team you are attacking? I have not noticed that my team is powering up any faster that what they usually are. Also can you only fight the teams you are paired against? Is there a way to choose some other team? Not a big fan of this Raid Tournament.
