Sigil of the Empty Throne
Whenever you play an enchantment spell, put a 4/4 white Angel token creature with flying into play.
This looks like a neat Johnny-tastic card. Maybe there's a mono-white enchantment control deck waiting out there, where this could be the win condition. With Idyllic Tutor, Greater Auramancy, Oblivion Rings, Runed Halo, and Story Circle, the defensive backbone of a deck is there. Throw in this new enchantment, and lay down the beats after a Wrath of God. In any case, it seems to have higher build-around-me potential than Hoofprints of the Stag, which turned out to be a bust.
Or, just pair it with Enchanted Evening. Hello, card advantage!
