Strange Tales #182

Loki, stuck on Asgard, launches a plan to help remove Thor from the equation. Discovering the powerful Doctor Strange he plans on tricking him into stealing Thor's hammer. Using a projection of himself, he convinces Doctor Strange to weave a spell that steals Mjolnir right out of Thor's grasp. Soon thereafter, Strange discovers the trickery, but is it too late? Loki is more powerful than anyone he's ever encountered before and so it doesn't look good for the Master of the Mystic Arts.
