I looooooove 2v2 so I'll give you some pointers.
- Use Uair defensively too. I saw some of your matches and you had some great uses of Uair but there were times where I was hoping you'd save your partner and you didn't.
- If Marth's spamming fairs just DI up and away or UpB. If you're on the ground, dtilt.
- Whenever someone is falling, charge an USmash. If you think you can hit with it, charge an Usmash. Hell, if you see someone coming, charge an Usmash.
- UpB when snake dThrows you.
- AMG PLEASE BUCKET THAT WADDLEDOO!
- If an MK uses upB and it doesn't hit you, you should instinctively use uAir. Maybe it doesn't lead to anything, but it gives you control and refreshes moves.
- If someone is spamming a kill move and you're at 100%+, get the hell away from them. I saw a couple of times when that snake spammed uTilt and you kept going at him until he killed you.
- The most important tip I can give you is: this isn't 2 1v1s going on. You're a team. Act like one. Be aware of where your teammate is at all times. Playing GW in 2v2 is a blast because you have to be aware of everyone (which isn't so for some characters). Just keep practicing with your teammate and talk things through. What to do when you're 2v1 vs some chars and so on. Communication is key.
-- The Matches --
The first match went mostly ok, until you two had that Marth alone. Then you went all reckless and could've easily lost. He took 3 stocks from your team and had you at 100% damage, which would've been enough for you to die from an upB. Try to get some more practice with your teammate. Learn to adapt to his/her style and choose someone to go first. The other one just stands in the back waiting for a grab.
I think you got lucky at the ending of the second match. Same thing happened when you were 2v1.
Third match was pretty bad. You got outsmarted, outdamaged and outstocked (obviously).
Fourth match was good, but same thing. Communication.
Fifth match, excellent use of uair!
Sixth match, holy crap, I thought you had a full bucket.
7th match was beaaautiful. Great example of Uair usage.
Anyway, your GW is pretty good. You have good control of him and you anticipate your foes. I was entertained by the videos. Sorry I went a bit dry on the matches, I'm a bit tired. Good luck and keep training!
