When you pick your ''teacher'' to wrestle against in CAW mode, simply hold down the LEFT trigger on the controller (the Z button on a joystick) while you press the A button to select your opponent. Press and HOLD both buttons until the blue loading screen appears.
Once the training match starts, the CPU should be controlling both your character and your opponent.
Now your moves will still get leveled up and you will still learn new moves even though you aren't controlling your wrestler!!!
Note: If your wrestler is at a high level, set the CPU difficulty to hard in the options or the match will be over very quickly.
All you do when you pause the game is press x+y. It causes the black menu screen to clear up letting you see the game screen. This will help a lot of folks trying to see what moves they are doing as far as the Create a Wrestler Option goes.
First of all, learn Powerbomb and Giant Swing/Giant Spin. Also, you'll need the Brainbuster to Kaiten-suichoku-rakka (Spinning Sheer Drop) Brainbuster combo. It would also be advisable to learn the tie-up F,X stomach punch.
Build up both the Powerbomb and Giant Swing/Spin to level 50 (have to hit those moves at least 246 times). The Powerbomb will unlock the moves Splash Mountain (in two forms - DFx2, A+B from standing, or as a combo from the tie-up stomach punch) and the Giant Swing/Spin will unlock the Throw Away Giant Swing (from standing HCF [half-circle forward], A+B).
Combine one of the two Splash Mountains with the Kaiten-suichoku-rakka brainbuster, and that will give you the Build-Up Buster (from standing 360 degrees on the joystick, B).
Next, delete the Powerbomb, and learn Piledriver. Combine the Piledriver with the Throw Away Giant Swing to get the Build-Up-Driver (from standing, 360 degrees on the joystick, A+B).
Finally, to acquire the ultimate move in the game, the Giant Gram (from behind opponent, 360 degrees, B), simply combine both the Build-Up Buster and the Build-Up Driver.
For any of these three characters, build up to MAX level, and press X + Y. They'll throw off their masks.
In the case of The Master (Keiji Mutoh/The Great Muta), unmask and you'll be able to do the Poison Mist attack by doing D,F,X.
To unmask Vader press X + Y during game play when your spirit level is on MAX.
