Stronger than other cards of this type that I've seen before. Multiples in draft would be very annoying, it's the kind of card I would pick.

And probably too strong. For W you're nullifying any creature P>2 and any other creature with P=1. There is no reason not to pick 4 of these and grind out every game, especially with removal at a premium, which it always is.

What would you suggest to adjust him? Mana cost up to ? Activation of ?

Maybe both. All I know is that if I can start clamping down and gaining life on turn 3, I'm doing that because there is virtually no way a draft deck is going to put enough pressure on me by turn 2 to make this card unattractive.

I'd raze the Activation then you have to balance using him and playing something on turn 3,4,5. Do I play this guy or do I save mana to activate this guy.
