I feel like this character is super gimmicky.
The only not gimmicky setup (no gaps) i know of for a grab set up is if you have two ankhs out in trait release them, then immediately after the df3 press f2db2, after they block this you can do F2db2 df3 f2db2 for pressure if you think they might not respect your advantage, or grab them for a full combo.
Edit: jk, the block pressure is all good but if they are holding back instead of down to block, our little T-rex arms will never reach them for a grab. I swear whoever designed this character was deeply confused about how they wanted him to be played. I wonder if the fact that alternate special moves exist means that in future patches swapping base special moves with the unlockable ones would be a simple way to balance characters.
