idea for magic system need one more category

I got 3 forms of magic

Space magic allows users to teleport themselves or others. The range of the teleportation is limited and get further with time and practice. When teleporting momentum still applies so if they teleport to the ground while for example falling at a high speed they can still break their bones when they hit the ground. Skilled users can create and hold for a brief time areas that loop into each other. for example if you walk through a door it will loop right back into the room that you where in.

Mass magic allows users to make thing heavier or lighter when they touch it. A example would be that a mass magic user can pick up a car making it only weight several lbs and throw it. Once it leaves their hands in revert to its original weight.

Time magic allows users to fast forward or rewind themselves (think tracer from overwacth). They can also pause time in limited range around themselves.

I need one more category of magic that fits into this group.

 

I think that is a awesome idea! I really like the calorific cost for using energy magic. When I read your post I kept thinking about a anime I saw where the main character uses electricity to launch a coins.

I was talking about this to a friend of mine and he believed that mass magic compared to the others groups was too weak. So I was thinking about changing it to gravity, It would give users abilities similar to mass magic however, it open them up to using other techniques.
Thanks for the responds
