Yes, and I like how Doom tell thems he is shutting down his offensive weapons and his force field. He did use that his force field no avail against a demon in Astonishing Tales #8 so maybe he doubted it would work anyway. But he made good use of recording his onboard computer system to analyze the other contestants spellcasting to help him learn on the fly during the contest.
Looking back at that page from Triumph and Torment where the "call goes out to all practioners of sorcery", I wonder who the unnamed sorcerer from Atlantis would be?
