Ive been testing openings for elemental,
I think now that the best openings in rank order are
1. 3 earths 1 mining
2 3 earths 2 mining
3. 1 air
4. 1 earth 1 water
5. 1 fire
3 earths is your best choice because v order your opponent will sword wrath mass which solves any problem you put to them the solution get an economy boost and a 1 earth advantage by the time your opponent has made 1 sword wrath.
Players can now take down earth and water even if u combine them because they sword mass.
