A new KOF98UM:FE match was uploaded by Emillll last night, only just had a chance to watch it just now though.
Some really nice play with Lucky in both matches, i've not seen much use of him in Japanese matches so it was refreshing to see.
I do remember reading a tier list a couple of years back where Lucky was considered low tier in the original 98, i'm not quite sure where he is rated in this game, but i always thought he was quite decent in 98.
There used to be a player in the UK with the nickname 'Kensou' who was a really good Lucky player, though unfortunately he no longer plays.
Also as you can imagine with a nickname like Kensou he used Kensou's fireball incredibly well. Almost down to a fine art, where you would jump and almost always he would make you land on his fireball.
