uhhh, which is it? Does captain falcon's start at 0 or 52??
I thought he said falco. Since Falco and Wolf are the only characters Wario can't CG starting at zero.
Patterns Try to pick up on the patterns that the MK are doing and pick your spots to get in on. It seems easy but MK has a lot of moves that he can through at you to attempt to keep you out and they're pretty much faster than what Wario has to have.
Punish Ah this is most likely the key element. You have to know when and how to punish MK. Because of how light he is you can punish him hard and get early kills(waft) The problem however, is the speed of his moves. Then there's also times when you can fail to punish. One of the common things for me is shield grabbing his dsmash. I will think I'm in range of to shield grab dsmash but I'd go for the grab whiff and eat a dsmash. Be wary of this. This is just one instance though and doesn't mean you shouldn't try for it however your spacing has to be on point. Since some MK's will throw it out there because they feel as though it's safe.
Patient While trying to get in you will take damage. However, you need to remember to take your time and think. Pick up on the MK's patterns and punish him hard for his mistakes. If you rush him you can either eat a kill move or take a lot of damage. Remember risk for reward if the risk out way the reward you shouldn't go for it. Always remember time is on your side. If the MK starts to get the feeling you're willing to take it to time or just aren't willing to rush they can sometime gets antsy. Waft is your best friend don't neglect him. Also try not to run into any grounded up B's invincible on start up.
You want the MK to come to you so that you can shield grab his stuff. You can come in on the MK if you like to apply pressure however, you have to be extremely careful since the majority of his moves beat yours out. Look for your spot and pick your spot to attack. I make it sound easy and it seems simply enough however, it's hard you have to play tighter against MK then any other character. His range and speed and low cool down make windows to get in and punish tight. I can't really tell you what to punish or how since it's spacing dependent and dependent on his move. You need to have a good feel for his speed and range of his attacks.
Hope this helps. Vids to look for fiction, hunger, bassem, blue rogue, krystedez should all have vids of the MU. Same with Masky. If any of them have similar play style to you should watch what their doing. ALso PX and Malcolm may also have vids of the MU. Also there's no real CP outside of like FD.
