One-way - YES, IT'S VERY OBVIOUS. Left side red, right side blue; vice versa when flipped. Dead obvious. Like having tea while sitting next to the 800-pound gorilla. You can see him, you can SMELL him - you can't ignore him.
I look at this deck and this is what I see.
An Ace of Spades made of clip art.
Two jokers made of clip art.
A King with a clipped-in two-finger peace sign - about the most original idea.
A riot of red, white and blue colors everywhere.
The Bicentennial just called - they want their tacky style back...
What's not to love?
Practically EVERYTHING.
There's too many better decks out there - I pass in spades.
