Drag and drop characters to create 5 man teams until your entire roster is used. This will utilize your entire roster without duplicating any character in multiple teams. When you're done, just open blitz, set the team and tap the save button - repeat until you have all of your teams saved. This isn't pretty, it doesn't import your characters or do anything cool like that, it's just a quick tool to put together your roster in teams without any overlap. I built it in about a half an hour, to run on my desktop fullscreen, so I can see the entire list in one page. I find it helpful to keep MSF open while you do this, so you can try and put together characters with similar power. This does not save your progress, so if you leave or refresh the page, it will reset - print the page (save as PDF) when you are finished.
