Loox is a relatively cheap card good for when you want to quickly add a monster to the board, or injure a monster in order to have Asgore kill it when placed. Also good if wanting to set off Mettaton NEO. Useful in most decks, but in particular Bravery Zoo/Rush, and Justice.

As of Beta 8.1, it's ability can use on anyone, making it a weaker, cheaper version of Vulkin.
