Finally someone else who realized the power of precognition! I voted other & specify: Lower the attack. An agent either is a spy or a good attacker, 4 attack is too much. Lower it to 2, 1 or 0.
If you want better card art, I will be using this sketch I did some time ago in Photoshop to create some kickass art and I think it'd fit the theme better than that picture from an old spy movie. You could rename the card and call it "Watcher" for instance to fit the darkness theme better
Not sure how I'd really use this card. I mean, taking a glance at the opponent's hand is nice and all, but what purpose does it serve? I would just +1 the initial cost of each and make each upkeep zero.
