'American Idol' Trading Cards! Collect all 138!

How many Sanjaya Malakar's equal a Katharine McPhee? Is it the same ratio as Stanley Nickels to Shrutebucks, the ratio of Leprechauns to Unicorns? "American Idol," along with Upper Deck, is releasing trading cards. They are set to launch April 21st and will feature a variety of past contestants, plus the judges and Ryan Seacrest. I feel like the Seacrest card should be the really rare one, rimmed in silver and all sparkly.

The cards will have 138 total that you can collect and are being sold in 5-card packs (5? That's it? My baseball cards used to come with at least 10). Six cards autographed by past Idols will be randomly slipped into the packs. Sort-of like Golden Tickets. Except with out the creepy child-mangling chocolate factory.
