j.D will likely hit 720's invincibility and leave us helplessly falling towards your glowing hand of death. I usually just IB and jump back and hope for the best. Every Tager is different, it seems.
Anyways I play this matchup terribly... I camp the fuck out of Tager with Optic Barrel. Yes I'm 100% sure this sounds dumb on paper but it seems I'm more likely to get fucked by approaching him than I am by letting him approach me. All of his aerials are insanely easy to 6c anti air and it seems to be safe on block. Every once and a while I'll mix things up and rush him down but not too often.
Every once and a while I'll fight a Tager who knows some corner Collider shenanigans, but it's a free air super as long as you don't start it right next to where his palm is. (lol at getting grabbed out of air super)
I'll post a video or something sometime but let me stress that I don't claim to be some great Noel player or anything, I just like this matchup and it seems like my strategy works pretty consistently for the most part.
Btw if you're magnetized and he does a random 720, you can fly like halfway across the screen with 2d right into his face, lol.
