I saw a graph with those 5 as the primaries and he uses bursts to accelerate himself and his bullets, which the graph showed burst as a combo of lightning and earth actually.

Here is a picture of the graph I saw. I just need to know what combo would be best to create a burst. If you don't want to use this that's fine, it's just a fan theory.
