Anticipation

[Phazon]

What does the effect "anticipation" actually do?

 

[Persona]

All the ability does is warn you when the opponent knows 1-hit KO or super-effective moves.

 

[airconditioning]

Basically, if your Pokemon shudders, it's going to get killed.

It's doesn't actually do anything other than though, so it's pretty useless. And if you really need Anticipation to know to switch out your Croagunk when Alakazam comes in, then you really don't have a chance anyway.
