Please capitalize the card name so we get the rules text popup and don't have to go searching for it.

The problem was that it wasn't looking for a non-land permanent; it was looking for an artifact, creature, or enchantment (somewhat understandable, since that combination's mislabeled as "TYPE_NONLAND"). So it could target Dryad Arbor or Ancient Den or animated manlands, but not planeswalkers.

Detention Sphere fixed in 714e57b. There's some 67 other grep hits for TYPE_NONLAND, TYPE_NONARTIFACT, TYPE_NONCREATURE, or TYPE_NONENCHANTMENT. I don't know yet how many of them meant to be e.g. "anything that's an artifact or land or creature" instead of "anything that's not an enchantment" yet; even those that are, I'm inclined to replace with the straightforward TYPE_ARTIFACT|TYPE_LAND|TYPE_CREATURE instead.

(Turns out the majority of TYPE_NONLAND should just be TYPE_PERMANENT; the rest are evenly divided between correct and incorrect.)
