MTGNexus

Previewed here:

An answer to field of the dead that can also fix colors. I don't think it's good by any means, but I think it fills a couple niches in casual.

It's an alright card, and it's flavortext proves that Nahiri is indeed the villain of the set, beyond any reasonable doubt. And that she will come into conflict with Nissa.

Spreading Seas, is that you? You seem.... different.

Anyway, this looks like a potent land hate option (and counterpart to Cleansing Wildfire), assuming you're hating on utility lands. That said, it doesn't have islandwalk synergies, and you can't use it to color screw someone unless they're already at low life, so it's a bit weaker overall.
