@ discozombie- who are you?
hells yeah this is he, and i was 2nd in my first green dragon tourney with stompy, and  the savannah guys came up that time too.  (the green dragon meta was strong then)  they laughed at my cursed scrolls, but they died to them the same.  so i have some experience, but i see the necessity for null rods and seals.  null rod for mana attack (ankh, maze), and seal for meta.  don't doubt cursed scroll tho.  it's techy.  i do like APE's last list tho.  sb needs some work

the ground seal should definitely be in the board.  the null rods are not as effective as you think they are.  the Genju of the Cedars should be 2 or at most 3.  trinisphere is still a big threat even with what should be 6 scrapper/scavengers and 4 zealots.  it shuts down your land grants, and you run so little land that the possibility of getting more is slim. more land or llanowars would help.

rather than offer criticism and be a T1 elitist (pronounced: asshole), i offer congrats on an excellent thought path, experience and most importantly solutions.

treetop village is sketchy, but synergistic.  i think that 2 is the better number in my opinion. i already talked about the Genju of the Cedars.  null rod is tough, but i ran cursed scroll.  don't laugh or downplay it or flame spray me, but it actually works, even with winter orb.  i used it for those last few points that stompy needed, and for occaisional creature removal.  it can get welders, aid killing juggs, kill people, slip past control.  the rancors also help with juggs and smokestack.  so here's my solution:

4 Hidden Guerrillas
4 Hidden Gibbons
4 Scavenger Folk
2 Elvish Scrapper
4 Viridian Zealot
3 Werebear
4 Llanowar Elves
4 Ankh of Mishra
2 Cursed Scroll
3 Winter Orb
4 Root Maze
2 Genju of the Cedars
2 Rancor

4 Land Grant
4 Elvish Spirit Guide
2 Treetop Village
8 Forest

board:
4 Xantid Swarm
4 Ground Seal
2 Cursed Scroll
2 Null Rod
3 Druid Lyrist

take it try it prove me wrong.  also, if you want some draw, try skullclamp or glimpse of nature.   if you have the power, replace at least one mana dude with a mox, and a forest or another mana dude with lotus.   alright, give me your criticism.

remind me again why aquamoeba is being used more than merfolk looter?  is the three power body and constant madness outlet better than drawing a card?  or is it replaced by bazaar?  
congrats on the win.

how do you own tog or keeper?
i have a lot of problems even though i have 9 counters.  i'm currently boarding 4 chains, and i still get owned.  pretty much let's face it, you have no draw engine vs keeper (brainstorms and FoF vs brainstorms and scryings) and the same vs tog (brainstorms and FoF vs brainstorms and ak and da and duress).  again, what do you do?

sorry i won't be able to win another greg's tournament.  just my luck.  have fun with what should be my mox whoever wins it.

4 creatures!?!
how can you expect any consistency?
tog? kill yourself.  how can you protect tog w/ only 8 counters? looks like a big swords target.
for the current metagame, i think that ascendant/ trike/ woodripper might have a chance.

what's the best 3 creature build for oath?
so many choices..
morphling
spike waver
spike feeder
trike
ascendant evincar
peacekeeper
crater hellion
woodripper
phantom nishoba
