Well, same advice I got, Birds of Paradise over Llanowar Elves. Also, on the sideboard have you considered Red Sun's Zenith instead of Devil's Play? One last bit: where are your dual-colored lands?

Oh, I forgot to mention: nice combo! If you can get it going early enough it's much faster than mine. I like the combo of Mulch and Noxious Revival .

Yup, Birds of Paradise over Llanowar Elves. Any color is better than just green.

Also, Manic Vandal is your friend. I ran a similar deck and I always liked drawing the guy. Another, stronger creature is Oxidda Scrapmelter.

I suggest -2 Wurmcoil Engine, -4 Llanowar Elves, -2 Ambush Viper, -2 Mulch

+4 Manic Vandal, +3 Oxidda Scrapmelter, +3 Birds of Paradise

My deck is Liquimetal Crush

Just kidding, that link is to another deck.

I'm not running Birds of Paradise cause I don't have any. The Elves are for at least getting ahead of mana so I can drop my bomb a turn or two faster. (being Wurmcoil Engine)

Same goes for the duallands, I would love to put them in, but I don't have any. This deck is what I could realisticly make with the cards I have. When I get my hands on an affordable playset of BoPs or lands I'll def. put them in.

Red Sun's Zenith or Devil's Play is sort of a tough choice, but I think I like Devil's Play better since if I get to cast it twice, that should be the end of the game, and it's resistant to mill strategies. Whereas Red Sun's Zenith is just gone after mill, and I have to hope to see it again if I cast it. It's a tough, nearly 50/50 choice on both of them tho. Would you take RSZ? And why?

I put in Torch Fiend instead of Manic Vandal cause I can choose when to blow him up, and I'm not reliant on a Coating to be there when I cast him. The 1 toughness is a slight problem tho, but I don't have to hold on to him if I can't blow up an artifact. I'm still torn between the two. If anyone can convince me Manic Vandal is actually better, I'll swap them around. Oxidda Scrapmelter will probably get a place in there. Perhaps -2 Manic Vandal, -1 Mulch and +3 Oxidda Scrapmelter or something.

Ambush Viper is one of the best removal spells in green right now. They're in there to deal with cheap offensive creatures in the format (like Stromkirk Nobles and such) cause I'd rather use my Liquimetal Coating on a land than a 1-drop. Also, Wurmcoil Engine is my finisher, I wouldn't want to take him out.

Thank you guys for the input, I'll keep tweaking this little by little while I gather all the cards I need.

The reason I like Red Sun's Zenith over Devil's Play is that you can potentially cast it multiple times beyond two, it exiles creatures it destroys and its cost doesn't increase based on the number of times you cast it. Those are my reasons, A Charmbreaker Devils could help though; it could be kind of nice for this deck, actually.
