i have tested them both, and let me tell you, when had them, i had really wish they were lead the stampede instead. just because late game, they suck, late game with lead the stampede is usually great, especially with my mana dorks.

i would say replace sacred wolf with Strangleroot Geist, but definately +1 for the deck looks quite good

Moldgraf Monstrosity.

maybe just 2 Creeping Corrosion's in the sideboard would be enough. the other two slot's would probably be for a couple of more specific card's for deck's viable in standard format. Nihil Spellbomb's or Grafdigger's Cage's might be more useful in certain stuation's e.g. swapping them out with Bellowing Tanglewurm against Splinterfright deck's. maybe you could add some green removal. Ambush Viper and Prey Upon suffice this considering how big your creatures are/will get, just incase you get into a tight spot. otherwise its a sound deck. it kinda bugs me that some apostrophes are put in the wrong places so this post is now plastered with gramatical errors

Almost forgot. Lumberknot

I'd cut the Overrun down to 3 and Bellowing Tanglewurm down to 2 or 3. Both of those are the kind of cards you only want to see once in a game, especially the wurm because the second one you play is just a 4/4 intimidate for 5.

Predator Ooze isn't a very good card and you should probably cut it. I'd swap all 4 for Strangleroot Geist. Think about it, the geist comes down on turn 2 and pounds for 2 immediately. By turn 5 he has done 8 damage... possibly more if he dies early. Predator Ooze comes down and does nothing on his way to 5 damage by turn 5. You will probably be able to ramp out the ooze on turn 2 but it still takes 4 turns for the ooze to out-damage the geist, once again not counting if the geist gets a +1/+1 counter. Versus black removal they are about as good as each other because the geist survives edicts and -x/-x spells once but the ooze can eat Doom Blade and Go for the Throat all day.

A possible alternative to Lead the Stampede is Tracker's Instincts since with the BoPs you can pay the flashback cost. In general I think I'd rather dig 8 deep and get the 2 best creatures from Tracker's Instincts than just nab whatever creatures I get from Lead the Stampede (stampede will average out to 2.17 creatures per cast if you stay on 26 creatures). Maybe run a split of 3 stampede to 2 instincts?

Finally, I think you've got to ask yourself what exactly are you ramping to. Increasing Savagery flashback is 7 and is very powerful but where are the big green beatsticks to help you break the stalemate? Chancellor of the Tangle can help you get an even more explosive start while providing a decent end-game body and is super cheap. Plus, with all the ramp you shouldn't have much of a problem getting him out. Engulfing Slagwurm, Garruk's Horde, and Liege of the Tangle are some other fatties that can help you win in the long run that don't cost a lot. Another option is to use a card like Jade Mage to give yourself a mana sink. Don't forget he goes great with Overrun.

Maybe cut some Overrun's, and Increasing Savagery. I really want to see Green Sun's Zenith and Strangleroot Geist in here! lol

Master flinter, you are correct about some things, but the only reason that i want predator ooze to be in this deck is simply because it wont die. the only thing that will be able to kill it is and Oblivion Ring but i will simply play down a creature that will end the game instead. and if i can get out some mana dorks, then play a wurm, then play a Overrun i will be able to wipe out my opponent. that s all there is to it.

i will however be testing the efficiency of Tracker's Instincts and Green Sun's Zenith . The only reason i might try to use Tracker's Instincts instead of the overwhelming stamped is because i can use it twice maybe, and i can play i turn two.
