Abilities not quite right. Wouldn't be mythic except that I'm running out of rare slots.

Synergy of uncommons and rares is much less; There aren't really any milling cards before this point.

But the idea is, you can have a joint milling/damage strategy, and then use this as a finisher :)

Or a pure mill strategy, and use this to mill yourself as needed to top up your life total and stay alive long enough to win.

I like it, but suggest that it be made a plainswalker (with enough loyalty to activate immediately) instead - more deserving of being mythic and a supervillain then.

Oh yes, I forgot to say, it should be good on yourself too, although maybe it's too strong if you have graveyard recursion and card draw.

You're right, would be a decent plansewalker, although (a) maybe it should only be activatable once, or twice, but I was curious to see if it could be more times (b) I never play with planeswalkers, so didn't want to design any for this set, I can't make them splashy without being insane.
