MONO-GREEN?!Thanks for all the upvotes!
The Creatures ♥
Arbor Colossus
It's a great wall coming down as early as turn three. He stops flyers, destroys flyers, and is a hero to devotion.
♥ Courser of Kruphix A huge advantage the longer this guy stays out on the battlefield. Not only is he the perfect blocker, he ensures a land drop every turn.
♥ Elvish Mystic Best and only turn one spell available to mono or dual-colored decks. If you want a turn-five or six card raping your opponent early in the game, you'll need two of these guys in your hand.
♥ Genesis Hydra Now, this may be the most underrated green creature in standard right now, in my opinion. That ability to drop a permanent upon cast is, indeed, "broken."
♥ Nylea, God of the Hunt What I love most about green is the stomp, but it can be pointless going up against an indestructible 1/1. For all big creatures in this deck, Nylea is the answer. Find with Chord of Calling.
♥ Polukranos, World Eater A wreck-machine of a creature, both early and late game. If things come to a doubtful standoff, use Monstrosity.

Scuttling Doom Engine
I based the deck around this creature, best as I sought. There are a lot of answers to him, but deal with him as fast as you can, because after his immediate attack, I've learned to sacrifice him with Life's Legacy. I'm not giving you the second chance to be rid of him.
♥ Sylvan Caryatid Lastly, but not least. The caryatid provides even more speed and acts as a shield against the weenies.

♠ Nissa, Worldwaker + Darksteel Citadel - Indestructible 4/4s.
