Hm. It's like Hivestone, but for a probably-less-useful tribe. Like Conspiracy, but without the choice (and without affecting cards in library and graveyard). Looks a bit overcosted, though I suppose it'll depend on what other Spirit tribal support there is in the set. I'd still imagine would be fine though.

fine with me :D

I think this would serve you better as an enchantment.

As an aside, there's a reason they printed Ashes of the Fallen in Kamigawa. I think players of Rise of Souls will be surprised by how many Spirits this doesn't enhance.

For what it's worth, though, as a person who plays with Ashes of the Fallen and Conspiracy in a half-Spirit tribal deck, I find that Conspiracy is too expensive by half. Great for what it does... but the choice to have half of your cards not combo with each other without Conspiracy on the table is a punishing enough restriction. I don't need the centerpiece enchantment taking up my 5 drop too.

But maybe I'm playing too casual, and there's a deck that breaks with cheap Conspiracy? Maybe. But I doubt that deck is Spirits, so I'm cool with a cost like this.

agreed

­Arcane Adaptation is pretty much exactly Conspiracy in blue but much cheaper.
