I thought it would be a good time to post the mono green deck I have been playing for a while now. It's basically 9 land stompy tweaked to abuse Tarmogoyf, the last piece of the puzzle to making 9 land stompy competitive.

Tarmogoyf gives the deck extremely good mid-late game staying power. And it got to replace Skyshroud Ridgeback, a card that while good early absolutely sucked in the mid-late game. It's been quite good and with just a little more very slight tuning I think could be viable...

Tarmogoyf Stompy

5 Forest
4 Wooded Foothills
4 Land Grant
4 Elvish Spirit Guide
3 Quirion Ranger

3 Vine Dryad
3 Rogue Elephant
4 Jungle Lion
4 Skaggan Pit-Skulk
4 Skyshroud Elite
4 Tarmogoyf
4 Street Wraith

4 Rancor
4 Briar Shield
3 Giant Growth
3 Might of Old Krosa

At zulanders suggestion, I cut 4 Wild Dogs for 4 Street Wraith.

I decided against splashing red for Kird Ape and others because it opens up the manabase to Wastelands and nothing other than Kird Ape improved the clok. Burn doesn't do as much damage over a couple of turns as a creature does, but it makes the opening hands far more inconsistent.

The 3 ofs were all cards that I absolutely hated seeing more than one copy of per game.

Quirion Ranger is the card hardest to justify as a 3 of. And I really can't justify that too well except to say that it does suck in multiples, isn't aggressive, and thus seems inferior to the other options that would have to be cut to make room for it.

Vine Dryad too is something that I hate seeing more than one copy of. It's only rarely as good as the card that you had to remove to cast it. And it's 1 power is a bummer.

I ran Rogue Elephant for a long time and am confident when I say that you never ever want to play turn one. Even played on turn 2, the tempo and mana it sets you back reduces how much you can do in subsequent turns and costs you more in the number of threats you have and how well you you can portect them than it gains you in it's one additional power over the other creatures. Tarmogoyf is infinately superior and an early Rogue Elephant makes it extremely unlikely that you will get the mana needed to cast it. This is why I hate seeing more than one copy per game, and absolutley loathe seeing multiple copies in my opening hand.

The 3/3 split between Giant Growth and Might of Old Krosa seems perfect.

Before I ran Street Wriath, I ran Wild Dogs. They are very flexible. You can cycle them when you're at lower life, or you can cycle them to put a creature in the yard for Tarmogoyf and draw an additional threat instead. But most of the time, they are a 2/1 for G which is a great bargain.

I would run Briar Shield even if it weren't for it's incredible synergy with Tarmogoyf. It makes whatever creature it enchants unblockable, lightning bolt proof, plus gives it +1/+1.

And Skraggan Pit Skulk has great synergy with the enchantment based pump.

The fetchlands are there for goyf but are really awesome for deck thinning as well.

As an aside, I tried Hidden Gibbons. It's perfect versus blue based decks. But against Vial Goblins, Affinity, 43 land, Vaka Pox and even Red Death sometimes, it was pretty worthless. Definately a 4x in the sideboard.

I also thought about Jitte and tested Winter Orb as the artifact for Tarmogoyf. It was okay but nothing special against a lot of decks like Goblins for example, and didn't seem worth cutting creatures for. Definately sideboard material.

A couple of Lotus Petal seem like a reasonable alternative to a couple ESG for goyf purposes.

On the same vein, can you guys think of any cheap flexible sorceries that you could run 2 copies of in the deck. I am trying to get atleast 6 ways to get each card type into the yard but Land Grant is the only sorcery I run.
