[Advice] Oath on a budget...

[Hoojo]

There is a sanctioned (read: no proxies) Vintage tournament that I really want to attend.  I'm not an experienced Vintage player, having only played in fifteen or so tournaments in the ten years I've played Magic.  I don't own any of the Power 9, nor any of the "cornerstones", but I do have the core ingredients to make an Oath of Druids deck.  I've been testing, and I've come up with the following list:

//Po' Oath

//Land
4x Forbidden Orchard
4x Wasteland
1x Strip Mine
2x Tropical Island
2x Underground Sea
2x Island
3x Polluted Delta
2x Flooded Strand

//Creatures
1x Akroma, Angel of Wrath
1x Razia, Boros Archangel

//Spells
3x Chalice of the Void
2x Null Rod
1x Mox Sapphire (borrowed from a friend)
4x Oath of Druids
4x Brainstorm
4x Impulse
4x Force of Will
4x Mana Leak
4x Duress
1x Vampiric Tutor
1x Demonic Tutor
1x Crop Rotation
1x Fastbond
2x Sensei's Divining Top
1x Gaea's Blessing
1x Rushing River

//Sideboard
1x Simic Sky Swallower (going to try to get another)
1x Tinker
1x Darksteel Colossus
2x Engineered Explosives
2x Oxidize
1x Balance
2x Energy Flux
1x Diabolic Edict
2x Pithing Needle
2x ???

Maindeck, I feel pretty good about the deck, but I welcome any advice I can get.  The Sideboard is my main dilemma; I'm expecting fish and powered Oath, but the meta is relatively unknown to me.  Any suggestions for varying metas would be most welcome.  I've researched other Oath threads, and have a few ideas, but would like to bluntly ask before I go on my own hunch.

Some card choices I have made might seem odd:

Fastbond: Since I'm not running very much artifact mana (one essentially), I wanted to test alternate acceleration without going overboard.  The single Fastbond has been great in the hand, and I haven't drawn it and been disappointed, unlike with Crop Rotation...

Duress: Since I don't have the power of Mana Drain, and I already run 4 Mana Leaks, I went with more proactive protection.  It's been a winner everytime, considering my mana development is slower than powered decks.

I've considered adding in Sylvan Library, cutting either Fastbond or Crop Rotation.  Crop Rotation has been the worst card for me; never had to use it to grab Forbidden Orchard.  I've grabbed Wasteland and Strip Mine with it, but usually only after I've gotten Akroma or Razia on the table.

i dont suggest running Tinker/DSC in the sideboard with just one Mox. Simic Sky Swallowers arent expensive at all, so it shouldnt be hard to get, but you must do so for Fish. Dont worry about your lack of power, Mana Drain isnt one of the key cards in Oath so dont worry, atleast you got a Sapphire.

i have played against several Oath decks using minimal power such as this before and they still do fairly well. As long as you've got all the needed stuff it should do well. Good luck at the tournament.

How do you only run 21 mana sources?  Oath usually has 23-25.  That has to be terrible against Stax.

I started with a base of 23 mana sources, but the effect on my draws was terrible, slowing the deck down incrediably, since it was 99% land.  I tried using Mana Crypt and Sol Ring coupled with the Mox, but again, the 2 mana makers were very unhelpful, being either one mana over or under what I needed.

I would consider:

-1 Fastbond/Crop Rotation
-1 Duress

+1 Island
+1 Flooded Strand/City of Brass

What would you suggest?

Any clue what the metagame's gonna look like?  A lot of unpowered decks, or no?

What about gimpy mana sources?  Lotus Petal and Mox Diamond might work...Chrome's card disadvantage is probably too much (atleast with diamond you're pitching a land...)

I almost suggested ESG for more turn 1 Oaths, but then I had to punch myself for stupidity.
