Pyxniel is a Magic affinity legendary from the High Elves. Pyxniel was introduced during a festive fusion event in December 2020 right after the Doom Tower was introduced and is a direct counter to Sorath the Ice Spider. Pyxniel also has good utility for niche Arena match ups such as Tormin, Gurgoh or any freeze champions. You will also get good value from Pyxniel against the Ice Golem.
Overall a mid tier legendary with some niche utility.
