Hey man not bad at all! Just a couple things I saw.
First off though, ness does NOT have a grab release on us. When he grabs us, our feet touch the floor, so just don't mash and let it come out naturally, and you won't eat a fsmash lol. The only way for him to grab release you if if you hold up(with tap jump) or push x or y to jump while in the grab.
1:03 You would want to bike away from the stage. It's usually the best thing to do. Biking toward the stage against a good player = gimp. Start getting used to that. It'll help. I only bike toward the stage when I'm already insanely high in the air, so it can go unpunished.
1:26 Don't get fsmash happy ^_^ It might seem like this great powerful, superarmored move, but if you whiff it, it's always a punish against better playes. Don't let that turn into a habit!
1:37 Nice Dacus!! :D
1:45 you already mentioned how you knew you were DIing that fsmash wrong, but now you know you shouldn't even be getting hit by it so it's all good ^_^
2:03 AHH! No Fsmash!! Use that to KILL! Shoud have used bite, or grab instead. Grab then the Fsmash. Instead of just throwing the fsmash out there.
2:34 sorry I just cringe everytime you get hit lol
Also, you don't always have to approach from the air. A lot of warios get themselves thinking that the only reliable way to approach is from the air, which might be true for some MU's, but Wario's ground game Isn't bad at all
I look forward to seeing more of you man.
