I don't play collectible card games (CCGs) much any more. If I do, it is usually with pre-constructed starter decks or with out-of-print games (like 7th Sea) that I can come by cheaply. I'm not so much of a "board game elitist" that I won't admit that I love these games though - I just don't have the patience or time for deck construction. After my first play of the Game of Thrones CCG yesterday I'm seriously tempted to buy some more cards and dig into it a bit more.
The key to Frenzy is the real-time aspect. There are no turns or order to play. You just lay down the cards as fast as your attention can keep up. The great thing about this is the game has just enought things going on to strain your mind, but not so much that you can't keep track.
Sounds pretty cool to me. The website indicates this will have a December release, but I don't believe it is available yet.
