Deity (魔人; Majin) is a family in the Battle Spirits trading card game.
It premiered in BS02. There are only two Spirits in this family, both of which are White, and are named after goddesses of Norse myth.
Given that a "Deity" family Spirit hasn't appeared since BS03, this is possibly a misprint of the larger family "Evil Deity". The Spirit Ur-Dine, which would go along with Ver-Thandia and Skuldia by lore, is part of that family.
