Light

The Light Element
The Light Element was thought to be the worst element for some time, until everyone can to their senses and realized that Nature is, by far, the worst.

Best Light Team
The best light team is:
 * Welder
 * Lady Robot
 * Constable

Alternate team:
 * Disco Diva
 * Santa
 * Fencer, Welder, or Lady Robot

Attack
Welder should put down both his specials to be hitting as many enemies as possible, and in combination with Lady Robot special it does great amounts of damage.

For the alternate team drop Disco Diva and Santa specials and then attack with Fencer regular, or Welder/Lady Robot special.

Defense
Someone should always be using Constable special. After they finish, someone else should start using it. However two Constable specials should never be going at the same time. Whoever isn't using Constable special should be attacking, and keep in mind that Welder and Lady Robot both have sponge, but they still smash rather fast.

For the alternate team the third minifigure heals through sponge using Disco Diva and Santa special's, and Fencer can use his special to jump away from the enemies.

Building
Welder builds very fast, but should not be used to build under fire unless the alternate team is being used, so someone should be distracting. Lady Robot is also able to build.

Solo
Always use the alternate team in solo runs, and you can build using Welder with Disco Diva and Santa specials healing him under attack.

Backup Minifigures
If you lose Santa or Disco Diva you can replace them with Robot, Alien Trooper, or Egyptian Warrior. But it is more recommended to switch to the other team. If you lose a minifigure from the first team switch to the alternate team.

Also, feel free to mash-up minifigures from the teams and use something like Disco Diva, Fencer, and Constable.
