With the meta switch, is Party Bus still good?

Yes, its still good, I just think everyone jumped on the mindlink bandwagon which requires an EPT, or else they went uber alpha strike with Party Bossk + another big. Not to mention Dengaroo who does the zuckuss thing better than anyone. It's kind of just been forgotten about. I've seen a few lists using it recently with TLT Torkil and such in some 4 ship scum builds.

I'm the only person I've seen who runs a latts party bus.

Her ability is great, especially paired with K4.

I run her with K4, Dengar, and Zuckuss.
