Smash Ace
I don't know if this is known or not, but during the absorption animation of the magnet you can do anything you can do out of a shield. You don't even have to press the shield button, you just hit the direction or jump button. You can input as soon as the attack connects up until Ness puts his arms back up, so it's a pretty big window.
This means no ending lag for PSI Magnet!
Of course, you have to have tap jump on to Usmash or PKT.
This doesn't work in the air.

Did some PSI Magnets in the middle to show what happens when you don't cancel. I also show what happens if you input without getting hit: nothing. Ignore the grabs.
