If you’re gonna use VT, it’s probably better to just do f.MP xx HP as a starter or something. I used this sequence in my CV; should work in this situation, if f.MP is fast enough to combo after uncharged s.HP after a dash, which I’m not sure about (If it’s not, just use a medium into VT and continue from there, or a medium into EX Orb):
CC s.HP, dash, f.MP xx HP xx VT, LP headbutt, (microwalk forward) charged s.HK, c.HP, ender of choice.
St.hp CC dash cr.hp xx h fireball>h tackle or ex tackle or h tackle xx super is going to be your best bet IMO.
You can autopilot the starter up to the h fireball then look at your resources and confirm what you want to end with. As an example if you have super then just tack on a h tackle xx super (516) if you don’t have super but have at least 1 meter you can just ex tackle (342), if you have no meter at all you can just h tackle (300)
If you have one meter and v trigger then you can ex tackle xx v trigger.
It all starts with sthp CC dash cr.hp xx h fireball and all variants lead to good oki save for super.
