The X-Men #93

The cover of X-Men #93 (1975) sets up a charged mutant-versus-mutant confrontation, with Cyclops unleashing a powerful optic blast while the silver-haired speedster Quicksilver dives in fast — their exchange of taunts, rendered right on the cover, makes the rivalry feel immediate and personal. John Buscema's pencils and George Tuska's inks give the clash real kinetic energy, with debris flying and the two figures locked in dynamic mid-air combat. "When Mutants Clash!" promises exactly that, making this a mid-1970s Marvel offering with genuine tension baked right into its cover design.
