My idea for a mono green devotion deck for Theros Block Constructed. Fairly simple, utilising lots of double green cost creatures to build devotion, then use that through Nykthos to pull off a big monstrosity with the Hydra Broodmaster.

Playing a small splash of white, using Temple of Plenty and Sylvan Caryatids in order to play removal cards to help deal with opposing planeswalkers and key enchantments.

Any feedback from those with some experience playing the current Theros Block format would be greatly appreciated.
