Hey Dru2,
There are some aspects of play that I saw that seemed to just be spacing/tech issues.
Try djc fair out of shield sometimes. You can often combo better with fair than grab. Remember, against heavier characters, it's harder to combo with throws.
Ftilt can be the safest thing that hits people horizontally! However I didn't see you use it very often, it can be good for whacking people away from the ledge who aren't sweet-spotting. Make sure to angle it up and down so you hit your target, even though it doesn't seem to make a big difference. Other edgegaurds are jump off and back air over and over dj teleport back, and dmash. Space that dsmash carefully! It's hard to hit, but the hitbox is bigger than the graphic is.
There were a few times where your djc techskill betrayed you. Make sure you can chain djc moves without making mistakes. Make sure you can do them and turn around and to them in the other direction. Make sure you can djc a fair and turn around grab. If someone unsafely does a crossup on the back of your sheild, djc a nair, and follow up with whatever is appropriate.
Practice dtilt into fair for when people DI your dtilt in. There was a time where you could have killed luigi on yoshis when you dtilted him because he DI'd in, but instead you did another dtilt which traded with one of his moves. Then you tried to do a usmash and he just punished you for it.
One thing that really got you punished is predictable teleports, especially from the ledge. It is necessary for every mew2 who wants to do well to learn to invincible stall on the ledge. If you don't, people will charge smash attacks on stage waiting for you to teleport back on. You can't ledgedash because of your dj, and you can't really ledge hop air very safely, which only leaves you with get up attack(bad), tournament winner(bad), normal getup, roll on, and teleport on. This means we'll be doing a lot of teleports. If we are doing a lot of teleports, that means we'll be getting read a lot! That means we need to figure out a way to shake it up! Watch the way Taj ledgestalls here in
SC4. He's rising up above the ledge and teleporting diagonally down back to the ledge, rinse repeat. The reason this is good is because you have the option of teleporting to many places all over the stage or back to the ledge. If the enemy stays on the stage, you get free ledge. If the misspace too much, you can normal getup, get up attack, roll, even tournament winner, or any of those usually 'bad options'. If they try to take the ledge from you, just teleport and center stage can quickly be yours. You can even anticipate that your opponent will try to take back their lost control of the stage rashly(especially since they'll feel robbed by a low tier) and go for a read. Mew2 can also do the same stall as fox, away on the control stick, upb towards the ledge- which is easier... but if you don't dj to get up higher and create options for yourself, all you can do is grab ledge, or choose a laggy option like telporting straight up, or almost straight up.
Anyway, work on that and you'll get to Grand Finals next time. ^^
