The Uncanny X-Men #367

Part three of "The Magneto War" arrives in April 1999 with a cover by Leinil Francis Yu and Jimmy Palmiotti that makes the stakes unmistakably clear: a power-wreathed Magneto looms in the foreground, crackling with pink magnetic energy, while two imposing figures — a dark-haired woman in green and a white-haired man — loom large behind him, forming the "Unholy Trinity" the cover boldly announces. Writers Fabian Nicieza and Alan Davis keep the tension building across this crossover event, and Yu's dynamic composition gives each of the three figures a weight and menace that pulls you straight into the conflict.
