Genesect not getting Earthpower or Superpower is really annoying. Especially as Superpower would give it the ability to actually do something to Heatran and Blissey in the mixed sets.
Delibird is pretty much unusable because of it's sucky move pool coupled with poor typing and stats.
I heard somebody actually made the nationals using a team based around Delibird for VGC.
Gengar not getting Nasty Plot really sucks since Blissey gives him problems without Pain Split or *ugh* Focus Punch...
