The 190 piece trading card set actually fits together to form it's own comic book with five unique stories revisiting the Kree-Skrull War. Each of the five separate stories not only tie into each other, but also the main Kree-Skrull War book.
Newsarama posted the details:
The 40-plus pages of stories include:
Each card has a front and back, with nine cards fitting together to make a two-sided page. The cards will be sold with nine cards per $3 pack, and 24 packs per box. Upper Deck will also have additional insert cards in the collection, including "cover art" for the stories.
"It's a real Marvel comic. It's the first time Marvel has done something like this, and it's part of continuity. And it ties into a major storyline, with the Kree-Skrull War," said McKeever.
You can head on over to Newsarama for more from McKeever and the five stories.
The Avengers: Kree-Skrull War trading card set is available this July.
