Big - O, my take (kinda weird).

[Zanetanos101]

Mana:
11 - Forest
4 - Wasteland
4 - Elvish Spirit Guide
4 - Bazaar of Baghdad
1 - Strip Mine

Creatures:
4 - Wild Mongrel
4 - Basking Rootwalla
4 - Arrogant Wurm
4 - Squee Goblin Nabob
4 - Troll Ascetic
1 - Spore Frog
1 - Genesis

Spells:
4 - Null Rod
4 - Survival of the Fittest
4 - Hidden Gibbons
2 - Naturalize

Sideboard:
4 - Oxidize
3 - Ground Seal
3 - Root Maze
3 - Maze of Ith
2 - Naturalize

Ok, so this deck is a little different than the traditional Big - 0.  Here are my justifications for each card.

Maindeck:
Mana Sources:  Self explanatory
Wild Mongrel: I hope this one is obvious, but the idea is to have discard engine/beatstick.
Basking Rootwall:  Free spell when discarded, very nice beatstick.
Arrogant Wurm:  4/4 tramples for 3 are nice.
Squee, Goblin Nabob:  Fuels Bazaars, Mongrels, and Survival.
Troll Ascetic:  Really hard to get rid of.
Spore Frog:  As was suggested to me, this plus gensis = tech.
Genesis:  Great versus control, good great synergy all around.
Null Rod:  Shuts down a lot of stuff.
Survival of the Fittest:  Tutoring/discard engine.
Hidden Gibbons:  Well 4/4s for 1 are good.
Naturalize:  Swiss army knife.

Sideboard:
Oxidize: versus slaver/stax/etc..
Ground Seal:  vs. Dragon.
Root Maze:  Shuts down most combo.
Maze of Ith:  House versus Tog.
Naturalize:  More swiss army kife.

I really don't think the wishes are worth a slot in this deck. This deck thrives on consistency and hate. By taking out the root mazes, you weaken a lot of matches. Also, the wishes slow you down too much for it to be worth while. Using both Bazaar and Survival means your mana will be tight as it is.

Also, I'd run two viridian shaman main instead of two troll ascetic. This also removes the need for the lyrist and shaman in the sideboard, and allows you to put in ground seal again, which is golden in so many matches.

Living Wish is bad - Survival is your tutor engine. As mentioned 1-2 zealots should be maindeck - along with genesis, a house vs. control, and possibly spore frog (genesis+frog wrecks aggro all day).

Not running wastelands+strip main is a serious mistake that will cost you dearly in all kinds of matchups - vs. dragon, vs. control, even vs. the mirror. Disruption is part of what makes Oshawa viable.

As an additional general note - posting deck lists without further write-ups/discussion is against the rules and can get you banned if you do it enough.

Oh sorry, didn't know that... Editing my post.

Dawnstrider over spore frog?

Dawnstrider 1G
Creature - Spellshaper
G, tap, Discard a card from your hand: Prevent all combat damage that would be dealt this turn. 1/1

Don't you find it difficult to get 2GG on the board every turn?  Sure, the Genesis/Frog combo is neat, but I speculate whether the manabase can really support it, especially in the turns that matter (mostly against FCG.)

[Zanetanos101]

Yes, I may have to reconsider that.

I've been testing O.Stompy considerably. Here are some notes:

1. You have way too few mana sources. 16 permanent sources is almost suicidal given that the deck is G mana hungry and you have 9 spells that require 3 mana. 20 sources, plus the ESG's, is the minimum.

2. Up to 4 Oxidizes belong in the MD. You need to worry about stuff like Chalice for 2, plus prison and Slavery style decks are your problem match-ups, not control - so there's usually no need to run MD Gibbons. Finally, Oxidizes are part of the mana denial package - if your Null Rods get FoWed, you still have Wastes for their lands and Oxidizes for Moxes. Naturalize is only good if you actually fear Dragon or Keeper's Humility, but you will get crushed by Dragon regardless so there is almost no sense in running enchantment removal.

3. If you're thinking of other aggro decks, then consider a lone Dawnstrider, either MD or SB (Genesis, by the way, is generally a waste of time - too slow). However, I cannot think of too many aggro match-ups where Dawnstrider would help. O.Stompy still has a great game against many aggro decks because of your potential for explosive creature development. Defensive cards like Frog or Strider are not part of this deck's game plan.  

4. Cut down on the number of 3 cc spells. I'd trim down the number of Ascetics to 2 or 3, and maybe reduce the number of Wurms to 3. Trolls were initially considered because they crush Disk-packing Landstill decks that frequently appear in Toronto metagames, but in other metas they might be too slow.  Play them in high numbers only if you expect lots of slow control decks (Keeper, Landstill), and only if you significantly raise the mana count.

5. Stompy is a metagame deck - treat it as such. If you expect lots of Welders, you can consider running up to 4 MD Ground Seals. If Tog is prevalent, then Root Maze deserves a look. Don't just wait until game 2 to beef up the MD against certain decks.

6.The SB is usually flexible in O.Stompy, but the prime considerations are always the following:

4x Tormod's Crypt - good vs Welders, Tog, Dragon etc. Lack of synergy with Null Rod is irrelevant.
3-4x Ground Seal - good vs Welders.
3-4x Hidden Gibbons - beef up your control match-up.
2-4x Naturalize - might not be necessary, but the added bonus of enchantment removal is good.
3-4x Maze of Ith - great anti-aggro choice, especially vs Tog. Buys you a lot of time.
3-4x Drop of Honey - untested yet, but could be good.

So, here is what I consider to be close to the ideal build, although the "hate" slots are meta dependent. The power can be replaced with Forests, but I include them because this is the Open T1 forum, not Budget:


Mana (24):
12 - Forest
1 - Black Lotus
1 - Mox Emerald
1 - Sol Ring
4 - Wasteland
4 - Elvish Spirit Guide
1 - Strip Mine
 

Creatures (17):
4 - Wild Mongrel
4 - Basking Rootwalla
3 - Arrogant Wurm
4 - Squee Goblin Nabob
2 - Troll Ascetic


Spells/other (19):
4 - Bazaar of Baghdad
4 - Null Rod
4 - Survival of the Fittest
4 - Oxidize
3 - Ground Seal


SB:

4 - Tormod's Crypt
2 - Naturalize
4 - Maze of Ith
1 - Ground Seal
4 - Drop of Honey/Root Maze

If you're certain you'll be seeing enough artifacts to justify 4 maindeck Oxidizes, you might want to consider Hidden Guerillas.  5/3 tramplers for 1 have their applications now and then.

Point taken, I will try to fit them in somewhere.

The Guerillas are not bad, but Gibbons are much more likely to trigger even against some of the artifact decks. I wouldn't connect Guerillas to Oxidizes though - Oxidize serves a completely different function, and plus, by the time the Hidden creatures are triggered it might be much too late.

@Zanetanos101: Is there a reason why you keep on cutting the Sol Ring? Sol Ring is very useful in this deck, especially when trying to muscle out a Null Rod asap.

Typo I think, my bad.
