They allow you to burn x2 TP per run for x2 the rewards/points, in essence you get 2 runs worth of reward in just one usual run. They also let you get event support/characters boost without needing to use the actual uma/support cards while doing your run, so you can still the most optimal things you have as long as you have stuff that get event point boost bonus.
