@Santo Amancio Well, after the confusion you can make your move depending on what they do. If they attack you, a djc nair wouldn't be bad, or a side dodge and disable/ftilt/dtilt/grab but you can also turn around and charge the shadow ball. Of course they can DI away, but after that it's your call. If they use their second jump you can easily strike them with a djc uair, nair or fair. If you did the combo on the edge try to spike them before they use their recovery move, then teleport to safety
@knihT I haven't tried it yet but I don't think that's a good strategy.I mean, we're humans. There is a possibility of miscalculating. Anyway, I'm not a Mewtwo pro, so if you want a good answer wait for Taj to reply
