The question is if it's actually also Ghost and not another Grass/Dark. We still don't have a Grass/Ghost so that's what we want. Besides, Grass/Ghost has fewer weaknesses.
Hmm...I just had a thought...if Ghost types can't be trapped anymore...would a Grass/Ghost that uses Ingrain still be able to switch?
Some people thought it would be related to Sudowoodo because they have problems with their head. We know for sure now that it's not a Rock type, and its second type doesn't resist Fire. I'm sure there are still going to be people who actually think it's related to Sudowoodo... unfortunately.
As for being trapped, I think that just applies to moves like Mean Look, Spider Web, etc. and not Ingrain. Grass/Ghost would be a cool type, though, and that's what I'm hoping for.
YOU WANT SOME FUNERAL TO GO WITH THAT CAKE? http://i.minus.com/ibeTNBZS1C6k9v.gif
