meh, I messed up in the framerate, it was supposed to say 27-29, which is almost at the end of the teleport. Mow has more information that I am missing, but I've actually been able to do a "fake" teleport, which is essentially a bug that the programmers never knew.
I can't tell the framerates on when to do this, but essentially what happens is listed below.
After performing the up-b, you must instantaneously press down-b at the same time, while doing an airdodge. For some reason, M2 performs a half teleport, hardly moving from his original position, and immediately performing a disable without any lag after the teleport. It looks very strange, but it seems that he also gains a few invincible frames while performing the disable. It doesn't look like he even performs a teleport, but rather an airdodge seemlessly integrated into a disable.
Here's a clue...
Riddle me this... Riddle me that... A mysterious infinitely teleporting cat
To do this you must... Have faith... Trust
In all of your instincts, the buttons are near
Frames closer to the origin of the teleport... I fear
For if too much info is given away
The disable will cancel, leaving your opponent in dismay
Practice makes perfect, don't practice too long
For who knows if the truth be told thru a song
A gullable child always seems to be accepting
The distant chain of info... always decepting
Just ask around as the famous one knows
The truth to this riddle, is found in the "snows"
A mysterious cat with tricks up his sleeve
Mewtwo is top tier... You will be deceived.
