I separate magical creatures from human magic users as they tend to have a spot of magic ingrained within them.

The Fairies are creatures that can alter size and use their wands as conduits and storage for their fairy dust. I say conduit because Blue and Nove both used magic without a wand, but presumably their wand had fairydust.

Mermaids just have portal making abilities and a nice voice. Ursula took the power of the Trident to change her form. Poseidon is either a powerful sorcerer or simply is truly a deity (which is something we don't know much about). Likewise, with Nyx. Jabberwocky was simply a monster cursed with immortality and fsome weird telepathy (which we rarely see).
