Traited D1 buffered into low grab is a good way to get Flash to stop dashing like an idiot and start walking. That's when orbs and MB pillar comes in and gets Flash anxious to get in, which then goes back to d1 grab haha.
I'll give my 2 cents even though no one asked for it
Couple helpful hints:
I usually stay in crouch block when not attacking because if he does torpedo it leaves him open for an air punish. I usually d2 f2d3MB grab b3 j3 tele f12push. Pretty decent punish off a d2.
F22 string one of the hits whiff. When you see it you can d1 grab. I think thats the right string...the oh one lol
Basic strategy is to zone and come in on your own terms
