CCG Computer Game

I was browsing the 'net once upon a time when I stumbled on a little
jewel of a game. Basically it was an online client where you could play
assorted ccg's (Dune, MTG, and Star Wars, I know those three were on
there...) against other players for free. That's right, free of charge,
you could download all the images for whatever game you wanted to play.
The only question remaining is: what was it called!? I can't remember
for the life of me. If anyone can point me in a direction. Any
direction. Thanks in advance.
