Despite all their planning and preparation, the League find themselves on the back foot as the Doom Star reaches completion. All that's left now is a last-ditch attempt to try and destroy it before the Father of Machines uses it to conquer the multiverse once and for all. Will the combined might of the Extraordinary League be enough to break Phyrexia's ultimate weapon, or will our heroes find themselves... doomed?

Stitch builds a pepperoni effigy; Luna reaches out with her feelings; Archer has one more for the road; and Mordin learns from the best.
