Witching Hour is a special character pack that not only adds two new characters to Marvel United: Agatha Harkness as an Anti-Hero and Scarlet Witch, for the first time as a solo Villain, but also includes the four alternate Hero decks that were previously available mainly at conventions: Grey Hulk, Juggernaut, Mister Sinister, and Deadpool (X-Force). To fully flesh out these alternate versions, this box also includes copies of their original game pieces, cast in their new appropriate colors. The back of their cards are marked as “2nd Printing” to distinguish them from the original convention runs.
