Take out some cards like sunchaser and Paragax Gaint. Really nice deck, I think what you are going for is a tribute red and green. There is some really good monster decks out there, and please put another Xenagos, The Reveler. I also see no god removal, you must put some god removal, everyone plays gods, they are the thing right now. But good deck, teak it a little and this will be one of those decks that wins games in FNM.

yeah i agree, I removed both Sunchasers and the Giant and added 2 Fade into Antiquity for the god removal (and for all the new nyx enchatments) and also another messenger Speed cause trample is really nice

I need to aquire another font of fertility, to replace one of the Snake of the Golden Grove, but im not too sure. Im not too worried about life gain and more about getting lands out

I like the fact you are keeping it in the Theros block, it limits you but makes your card selections that much more important. +1

The only sagacious advice I can give is try to go for more consistency. You have a lot of 1x or 2x cards which is nice for variety but bad for drawing. I'd try to acquire more copies of the cards you really like to play and prune the others.

Good luck!

If anyone would like to suggest m15 cards I would be very great full, I'm buying cards tomorrow and I'm not sure which ones!

4x Elvish Mystic for ramping to the big guys faster

2-3x Genesis Hydra big hydra who lets you get another card out for free

3x Ranger's Guile to save those big guys from a Hero's Downfall for a single mana

2-3x Titanic Growth throw on a guy w trample

3-4x Lightning Strike for obvious reasons

Check out my Gruul deck, Garden of Blood-red Roses for more ideas outside just M15 cards.
