Legendary: A Marvel Deck Building Game – Dark CityExpansion

From BoardGameGeek:

There is a darkness rising in the Marvel Universe! Legendary: Dark City, the first expansion to "Legendary: A Marvel Deck Building Game," brings an entirely new level of play to the critically-acclaimed card game. In Dark City, players use new heroes like Cable, Daredevil, Professor X, and Blade to face off against deadly, all-new Masterminds like Apocalypse, Mr. Sinister, and Kingpin! Legendary: Dark City features 350 all-new cards, including cards for seventeen new Heroes (including X-Force, X-Men, and the Marvel Knights), six new Villain Groups, two new Henchmen Groups, eight new Schemes, and five amped-up new Masterminds more powerful than ever before. Each Hero features four different all-new artworks. A new "Unique Bystander" mechanic gives special rewards to players who rescue them. It is now up to you to survive the Dark City and become Legendary!
