I don't like PS1 as much as I like PS2
PS2 has to be my favorite stage in PM
There is a reason why Lylat is on the second page
Although I will use it as a counter pick once in a while
The placement of the platforms gives huge advantages to certain characters while the stupid ledges really hate the people who are not favored. All in all I think it's an unbalanced stage.
A Dark deck abusin' GR's Mewtwo and Dark Clefable's Pokepowers is pretty scary... even moreso when used with a Dark Raichu as the main damage output. Even if there's just a small chance of 50 damage for 3 energy and 40 damage to all benched Pokes, that's utterly absurd. Particularly when Clefable occasionally gives ya a free Defender.
If Pluspower also works with bench damage, that's just retarded.
