Yeah sorry I can’t believe I forgot to put that in there. It’s one of the few times when you can actually use that super for something other than chip damage.
and even that way, is not that useful thanks to advanced guard. Is even worse if you do it like out of nowhere because they can super jump, air dash, jump and airdash and be safe.
Even more, characters that can stay in the air for a long time like Ken, Tekkaman or chun li can avoid it even easier. Casshern and Batsu can super jump divekick out of it.
The good things morrigan has are her fast pokes, instant overheads and being a good battery.
Also her air fireball is SLOW, and you can throw 1 and switch characters so that the fireball covers them (though a super with good priority or a LV3 will still rape you)
