You'd be correct in that. Ice is her go to, she used Wind once, and Fire Dust...3 times, technically, if you want to consider the White trailer as a canon representation of all her Dust types.

Gravity is what I think she uses for pretty much all her Black glyphs, which she can either make herself, others, and objects stick to and shift directions, like she did in the V5 trailer twice and several times through Volume 4, or decrease gravity above an area like she did with Bolin and Nadir from ABRN.
