Is the flame not coming out? or is the flame coming out but just not connecting?
If thats the case then maybe your doing the flame too slow. This usually never happens with me. But sometimes when im goin for that combo i get a b.LP which is his overhead chop lol. I usually just laugh when it connects.
I have problems also landing it consistently if at all. Although in training mode I’m not that bad… guess my execution goes down the drain in real matches… but anyways, try using down-forward, back, for the flame. It’s a shortcut. It helped me execute it faster and link with the b.mk easier.
Try this way : IAT HP, b+MK(input this command slow than before. Because of J.HP has 18 hit stun frame, b.Mk has startup 5 frame.) , LP Yoga Flame.
If you have super gauge, you can use it after LP Yoga Flame too. quite difficult.
