Eye was added in Beta 23.0. Previous Versions can be found here.
Eye's effect uses Bratty's lost half of her ability, which makes the enemy reveal all cards in their hand. Since Beta 40.0, rather than showing off the cards one by one (like Spy still does), it lets you see all cards at once in a "Choose 1 Menu". And you can indeed choose 1 card from it and increase its cost by 1G, which is more controlable, but less effective than Evil Eye.
Eye itself is a pretty decent card, being a 5/6 monster for 6G, making it slightly weaker than Aaron after its effect with +1 HP and Cost.
