Looks very good! Respect for the green devotion players. The only suggestions I would make is to use that white for some Banishing Light or Pacifism because B/W Heroic is a tough match up in the meta for green devotion. So even though you have Reclamation Sage and Polukranos it is easier and more efficient to use spot removial. Unless you side board 4 Back to Nature. +1

Thanks for the suggestions, Mr.grizzly. I think that's a good idea. A couple copies of Banishing Light in the sideboard does seem like a good idea. Kiora, the Crashing Wave is also quite good against heroic decks, but having some spot removal would be nice too. I will play around with that.

U/B is a killer against green devotion decks, I am thinking of some ideas myself, I play the mono iest of green haha and I am thinking about a Mistcutter Hydra and Pherixian Revoker combo with Ranger's Guile and Titanic Growth to buff for a quicker protected win, as a fellow green player what do you think?

Mr.grizzly, I haven't had enough time to test this particular version against control decks, but I feel like Mastery of the Unseen would work well. It allows you to keep putting threats on the board and they tend not to have much enchantment removal (unless they are playing Sultai Control) ... also, if Ugin comes down, the manifest creatures don't go away. Control has always been a tough matchup though for any green devotion based deck I have played. The problem I have found with Mistcutter Hydra is that they usually just spot removal it with Hero's Downfall, Murderous Cut, or Ultimate Price. If you are playing straight mono-green, I think the best tools at the moment are Whisperwood Elemental for board wipe protection, Nissa, Worldwaker for being fast and aggressive or recovering from a board wipe, and possibly Temur Sabertooth which synergizes nicely with Hornet Queen and Genesis Hydra. If you are playing with blue or black, Disdainful Stroke or Thoughtseize is great against control. Do you have a decklist posted?
