LOL, me and Taj both know Mewtwo dittos, are actually EXTREMELY ********... lol
Tech skill does come with practice, as for fighing the fast characters, that's something that only time, experience can really teach you. Hopefully someone in your area has a really solid, Fox, Falco, Falcon, With Mewtwo in battle you will probably, be Waveshiedling MORE THAN ANYTHING, in battle, this is just so you are able to move, w/o waveshielding "effective" movement would probably be impossible, Teleporting is key and very vital, Mewtwo's teleport is a gift, that no other has, with it's speed, and effectiveness, However, It's the only Up-B in game that deals no damage regardless, kinda like Mewtwo's D-smash (only character that goes in one direction) =/
Umm as for the ledge teleport, any stage w/a solid surface, that you can't go thru. so all the tournament legal random matches are fine for this, just it'll take practice to get down..
As for the edge, you might be there for a while to be effective, but Mewtwo to me, is actually a pretty decent edgeguarder, I use F-tilt and D-smash for the edgeguard, to hopefully set up for wall of pain B-airs or a simple teleport to edge, Mewtwo's tilt to me is nothing short of amazing! =D
Always, always, always try to have a full charged shadowball, it's an awesome projectile, kills at fairly low damage, and is hard to judge, since it waves up and down. =p As for shadowclaws, I recommend DJC shadowclaws.. so much more smooth, and effective that way, however timing also becomes more difficult too because of the small hitbox it has... As for recommendations of C-stick or not, I can't help you there, because I don't use the C-stick, (but to me, analog and a button is your winner) so I wouldn't know the benefits w/it or not.. =/
I guess you could say i'm his apprentice... =p and when he leaves, yeah He told me he's counting on me to continue what he'll be leaving behind... Nah, I don't have one yet, I just try and help as many people as I can to get better with Mewtwo, Taj and I both have the same goals, and that's to get Mewtwo to Low Tier, I just knew someone had to step up because Taj, can't bring Mewtwo to low Tier on his own, he needs some help, so I came in, and (hopefully other soon too) Cuz if the M2 were only Taj, he'd be considered "the exception" you know.. so yeah! n n
