Does Zod have access to any 50/50 mixups without trait grab?
The 3 in 213 is an overhead so you can do 213 or 21~MB ground blast.
213~MB ground blast, ff, f213~bf3 (you have to charge the lazer and stall the meter burn until they land. if they block the 3, backdash out of the lazer)
21~MB ground blast, j3, f213~bf3
There are probably better combos for this, but I really don't use it a lot. Check SimSim's combo thread.
