Not sure how to post a picture of the card, but I need to enter Mars Troll Clock's contest so.....
My favorite card is Seeing With New Eyes. Rogue.
I absolutely love it when my opponents attack knocks a few cards off my deck setting up the big swing back with this amazing card. How many cards allow you to swing for double digits on turn 2? If she connects, you not only take a big lead, but you also get to see a big part of your opponents deck and will know early which blocks to save. I think she can set up the game for you the rest of the way. Not only that, but she is usable even when your opponent drops one of those annoying keepers that reduces your power. Such a large attack for such a small cost seems amazing. She's not perfect. There have been a few times when I've had her ready to swing except for the fact that there is another on the discard pile allowing me to swing for 0. :(
She's not perfect for every deck, but I believe she can fit into many, many decks......even those brutal red builds.
So, let's hear your favorite card. It may be worth a shiny Thor statue for you. www.squadcards.com
