Hmm..
So first of all, it's a board-wide 2-turn stun. Feels kind of like a mini-Dimensional shield (though cards played after it will still punch yo face) while at the same time she has a Sniper ability attached to her, a random Sniper ability.
I like the idea, but I'm just still wondering if the cost and everything is right on it. I'll let more experienced card makers help you determine that.
