Card of the Day - Staff of Athreos

I'm kind of bummed that Born of the Gods didn't do the weapons of the gods. If Journey Into Nyx does, The Staff of Athreos might look something like this.

Bonus! Speculation - RTR Mythics

So we've had three of the five guilds in Return to Ravnica spoil a mythic rare with converted mana cost XAB (or XAAB in Azorius's case.)  I'd like to speculate what the other two guilds would have for their card.

On second thought, Trostani's Balance would be much more useful as an instant.
