Most peole know that Spawn is increadibly powerful. He can take most people on.
X-Men: Wolverine, Nightcrawler, Cyclops.
OR
X-men: Siver Surfer, Archangel.

One of those teams. Not both because thats too much, one or the other.

Setting: Spawn's Alley, at night.

if you can think of better X men team setup to make it more fair, please do!
