Ermmm... really shouldn't destroy creatures... or enchantments or artifacts or planeswalkers - especially not with a wrath effect. Maybe polymorphing, but that probably isn't in the flavor.

As this is, I would have it cost like or so.

This is a wrath with a huge mill on top; and then randomly another benefit, AND a 4/4 creature?

Even ignoring the "This is not blue" complaint; they don't usually print "Win the game" at four mana.

@Vitenka:

You forgot to mention that it has flash xD

Hokay. So. Now it's a mass-bounce (much bluer) and a mill. And costs 6. Looks almost reasonable.

And... it has carved out an exception so it doesn't bounce itself. Presuming that the set has a lot of other 'eye' creatures in it, obviously an "I win now" button for a deck built around them. Playtesting will tell whether that is problematic or not - certainly it's a thing to aspire to, and can be balanced.

And getting a total lockdown with it would mean being able to also cast, oh, Conspiracy which means it's difficult and fun to get to, rather than just horrible. (Obviously if it lands, you scoop, though.)

Oh, and it STILL has the extra "Scry or mill a few more" rider. Why does it have that? What is it for?

Well, let's see - what have we now. 6 mana, sorcery speed. Bounces everything other than eye or lands, and mills someone for a lot.

I guess that's the core of what you wanted it to do. It's still good - and simpler to uderstand since it doesn't have that rider. It's a blue-wrath, that also progresses either your "I want a graveyard I can use" or your "Mill them to death" objective. And the set does indeed have a few other eye creatures you can build around.

Which would probably make this not very good in draft, which is amusing - but hardly an unusual position for a mythic.

It's not Upheaval, but in a blink-deck it's still very nasty.

Since this card was first designed, you can actually use the word mill in rules text now!
