I tried to cast Island Banishment on a Seething Archosaur. The game wouldn't let me because it's "not a land creature." I've also tried it on Ulg Turtles with the same effect.

Is something with the "Swims" attribute not a land creature? How can it survive on land, then? Is it, then, considered an "Aquatic" creature?

Regardless, there's another card that affects "Land Creatures," that being Tangler. Tangler, however, can target Ulg Turtle and Grek Egg (both "Swims") even though it should only target Land Creatures.

So, which is it? Why are the treatments different for the term "Land Creatures" on these two cards?

It's bed wording of three cards:
- Undead Octopus, that have definition of land creature (non-Aloft, not Aquatic, can't Swim);
- Tangler, that threat "land creature" all non-aloft creatures that not in water (that looks wrong, should be "non-aloft creature and not in water" or something like that);
- Island Bahishment use same definition as Undead Octopus (should be changeg to blue keyword).

So I believe that Tangler is wrong, not Island Bahishment. And banishment should have blue keyword in description.
