Maybe there are problems with the image, but I don't think there are problems with the card name? "Otyugh" is a d&d creature, but is also an element card.
this is from their license
For the avoidance of doubt and in addition to the provisions of Section 9 related
to ownership and use of Wizards Intellectual Property (as defined therein), Licensee expressly
acknowledges Wizards’ ownership of all imagery and artwork contained in 4E, and Licensee expressly

without limiting the foregoing, Licensee will not reprint, publish, use,
nor create Derivative Imagery of, any of

Inc.): Balhannoth, Beholder, Carrion Crawler, Displacer Beast, Gauth, Githyanki, Githzerai, Kuo-Toa, Mind
Flayer, Illithid, Slaad, Umber Hulk’ and Yuan-Ti. looks like elements might already be infringing on atleast one of their properties
