I wouldn't say worse. Every pokémon has a different temperament when it comes to battling. Some like it, some don't. Others don't care either way.

[Marik isn't quite used to that dynamic yet. Kisara and Allura are about the only two that can get away with teasing him somewhat because he respects them.]

It was a normal tree. Spinaraks can be found in them sometimes and mine happened to fall out and on to my head. It wasn't fun.

[He blinks. He's only caught one ghost in the wild...]

I never had any trouble with the pokéball passing through them. They usually stay solid unless they want to hide or be mischievous but that doesn't seem to include pokéballs. It's weird.
