You dont seem to know Marios style so heres a BIG guide just for you^^
IMPORTANT GOOD INFO :
Read this if you want to get better!!!!
First lets review the video!
-You shouldnt to UpThrow against Middle Floaty characters (Bowser, Mewtwo, Marth)
You should DownThrow instead, ill tell you why!
With DThrow you can either start a COmbo (which is very hard to choose what you are going to do from these choices :
-DSmash (Do this if your opponent has high percentage or you just want to get him away from you)
-UpSmash (Do this to Combo FastFallers at pretty low percentages and to kill FLOATIES ONLY (Jigglypuff, Kirby)
-UpTilt (Do this to Combo Fastfaller at HIGH percentages (70-50 %) )
-FullJump Dair (I do NOT recommend this... DONT DO IT)
-FSmash (ONLY after
Now while we are at it lets check out the other throws :
-Backthrow : An OK Kill Move, do this near the ledge or try it at high percentages
-UpThrow : Great for FastFallers (Falcon, Fox, Falco) Mainly because you can Chaingrab them with UpThrow and after 5 UpThrows UPTILT THEM and COMBO THEM
Now you might wonder what I mean with ''Combo'' them... well heres what I mean :
When I say combo after a grab you should imagine a move like this :
Fox Chaingrab (4 times with 1Headbutt each (Very important to do 1 Headbutt or 2)) - UpTilt (maybe 2 times) - Uair Shffl ( against a Fox or Falco do Uair Shffl only 1x to Fox or Falcos they fly to far away and @ Characters who float middle or are TALL like (Roy, Falcon, Ganon, Marth, Samus do 2-4 Uair Shffls (you Dont need to l-cancel them actually) - Finish with a DSmash or FSmash or NAIR
Lets sum the Combo up and I want you to imagine the correct way of doing this combo : Chaingrab Fox - UpTilt (@High %) UpSmash(@Low Percentage (30)) - Uair Shffl - Finish (FSmash ,DSmash, Nair)
Alright now we have finished the Grab section...
Lets look at his approaches :
A good Mindgame is always to pay attention if youre opponent ist Shielding or not Shielding
If he shield alot then you should simply come at him with a JumpCanceled Grab (Press X and Z at the same time and experiment to get the timing right) with this grab you can do the stuff Ive written above.
If he is not shielding many times and you seem to know it now then just start goin crazy with Uair Shffls or a Nair Shffl approach to JAB (Tap A 2 or 1 time)
Now Ive said Uair Shffls and Jab...
Let me give you tips for this occasion.
Uair Shffls :
-You need to be good at this before you try it! (Be fast and do fast fall with good timing)
-Start with a low Uair (Do the Uair but only do it a tiiiny bit later so you can get him even if he/she is a small character (Doctor Mario, Roy, Pichu...)
--> Now after the first Uair youve done you can either Jab (Tap A and Grab or Smash or do something afterwards, I prefer Grab to DThrow this way you can Combo... AGAIN) or you can continue Uair shffling about 2 more times and finish with a Smash or a Nair maybe even Bair if your good enough.
I can say like so much more but im too lazy^^ I know all this stuff thx to Eggz, my fellow German Smashers and my own tourny experience (yesterday)
