Perish is a known quantity against Maverick/random green stuff, but I wanted to see if Dreams specifically was enough. If it was, then going Naya becomes easier because you can just swap Perishes in the board to Dreams and still be good against aggro decks.

Dreams has the upside of destroying lands, which is randomly useful in non-aggro matchups. However, Perish is more effective as a Wrath. So I dunno.

EDIT: I should add that Dreams was a 1-of in my board for testing purposes. I probably won't use it if I stay on Jund.
