-diddy Fsmash - SDI behind him -> jab to grab
-olimars uair - Sdi to the sides -> fair
-mk's fair/bair -> Bair is probably easier, so SDi to the direction where the attack points.
-ikes jab combo -> one of the easiest SDI, behind him.
-pikachu's Dsmash -> omg i did that already 2 years ago, and I didn't know what sdi was. Its a simpel human reaction.
-lucas nair/dair -> Dair is rather difficult. but nair better to should it and jabs back afterwards.
-lucario dair -> yeah great, buy me some new controllers because lucario just use this -.- but shield is easier too
-marths dancing blade? maybe? Yep. I think, it's the most difficult one, but really awesome. pointing hitdirection sdi or best is footstool (oh yeah) and same time nair. Marth gets touched you are in outrange because of the footstool.
-snake Ftilt --> jabs too. Ftilt just go behind.
-falco jabs -> yeah Sdi in him -> UpB guaranteed.
hum.. Maybe you should try to come in the top 25 again.
would be nice to see few luigis there.
