element groups.

[russianspy1234]

so i am working on a series of cards, but in order to finish it i need to figure out a good way to group the elements into 3 groups of 4.

one really popular way i have seen is
    |    | 
 i dont particularly like that one, if for no other reason than grouping them this way makes firerush/stall more powerful with my idea, so what is another good way i can group them.  i would also prefer not to have light and life in the same group

going either across or down the table from in the game also has  in the same group.  how else could i group them so it doesnt seem random?

All I can suggest is, Study the Scientific side of each element and you will learn how they are connected.

one way i see them is:
best at offense 
best at defense 
best at general countering 

[Naesala]

  Chaotic, energetic, bright
    defined, somber, dull
  persistant, eternal, edging neither towards law or chaos

not the greatest division, but it works

[darkrobe]

  - Heaven
  -Hell 
  : -Material World

Not sure if time and gravity fit here the best but its a suggestion
