Regarding your Infinite Illusion team, it sounds like you've got a good lineup for the Trial of Strength. As for the remaining two spots, it would be helpful to know what types of ninjas you have available and what you're struggling with in particular. That way, the community can offer more targeted advice to help you round out your team.
