Typical Light Teams
Here are the best element combos with light I know of, roughly ordered by preference, with their best fusion skills. In most cases variants exist.
Since their main advantage is obtained with just two titans to summon their totem, they are often used to support other elements - anyone pairs well with them.
Note that against other light teams you want your totem to trigger after theirs, so it may be a bad idea to use Rigel. But in other cases you need the totem early on to survive. It depends on what opponent you expect.

| 5/5 | |   | |
| 5/5 | | | variant for CoW defense |
| 5/5 |     |     | great fusion combo, full auto |
| 5/5 |     |    | great offense team, especially when played manually |
| 5/5 |  |    | |
| 3/5 | |  | good against fire+light |
| 3/5 | | | also good against fire+light |
All of those teams are only viable if you have two good totems. If you only have a good light totem, light is not the best choice alas. I am not sure what to recommend then, maybe a team with Tidus and Nova, since Rigel will die early on.
