This deck is a pretty regular mono-green devotion build, post-Fate Reforged. Notable includes from the new set are:

Frontier Siege: I've been playtesting with this as a one of, as I've had mixed feelings about the card. Dropping it on turn three after a single mana dork lets you cast another dork post-combat, giving you up to eight mana on turn four. Ugin, anyone?

Shamanic Revelation: People seem to have negative opinions about this card, but I've been impressed with it so far. If you can draw three cards (pretty easy with something like Mystic > Courser > Polukranos), you're getting great value. Of course, resolving it after a Hornet Queen is ridiculous, but by then you're likely already in excellent shape. Doing nothing on an empty board is a major downside, but by then the deck will already be struggling with the lack of mana. Two copies in the main for this one.

Ugin, the Spirit Dragon: Pretty self-explanatory. One of the best cards to ramp up to. Hard to remove, impacts the board immensely and his ultimate will ruin anyone's day. I may add a second copy (although he's rather expensive).

Abzan Beastmaster: This is another card I have mixed feelings about. He can net you some insane value, but it's somewhat conditional (albeit relatively easy to fulfill with hydras, polukranos, etc). He's currently a one-of in the sideboard to punish creature-light opponents, but I think after playtesting with him he could make the main deck, as a one- or two-of.

Suggestions/criticism are welcome.
