Couldn't find another card with this ability. Seems like new territory that could be explored.

Gibber. I've played with "Any player may..." stuff a bit, never thinking of using it seriously.

It's a bit interesting. It's obviously insanely efficient. But you'd BETTER have that regen mana up when you attack, or an opponent will steal it. And if they kill it their turn, they can get it. And Vedalken Orrery is, as always, insane.

I fear, though, that this is a big risk as a sacrifice outlet. Replace all "Sacrifice a creature" costs with ? Ouchie. Not that we were particularly considering sacrifice for this set.

It's damn interesting though.

yea theres a risk of casting it repeatedly. maybe add some cost when casting from the grave.
