Okay, since budget decks are getting discussed in the development forum I think it's not a bad idea to try and make a similar budget deck while staying mono white.
This deck will be made with the same budgetary rule's as Steven's decklist, meaning no cards that cost more than a goyf.
First up:
The Creature's that come to mind:
Ethersworn canonist: Hose's combo like a champ
Glowrider: Thorn of amethyst on a stick, but doesn't get bounced by rebuild and hurkyl's.
Jotun Grunt: Somewhat slow for ichorid hate, but still provides a decent clock while eating away welder target's and killing yards so Y-Will becomes less effective)
Samurai Of The Pale Curtain: Hose's ichorid like a champ (no cards go to the graveyard from play, so no token's and ichorid stays away)
Aven Mindsencor: Screws with Fetch, and all tutor's, really good against Tezz and Combo
Kataki, War's wage: The pain in the but for shop decks
Children of korlis: Make's combo take a while longer (finding bounce take's longer) and give's ichorid harder times by removing bridge's and gaining life to race.
Icatian javelineers: Ping's confidant's and other 1 toughness creature's.
Kami of Ancient Law/Ronom Unicorn: Kills annoying enchantment's but that about it.
Mother of rune's: So you want to bounce my glowrider? tap....
Hokori, Dust Drinker : on the expensive side, but with null rod, chalice and glowrider+Thorn your opponent will be slowed down a lot
I bet there's more but I can't think of any more...
On to the instant's:Swords to plowshare's: Does it really need explenation?
Path To Exile: Give them a time walk because of life gain, or give them their land right away? make your pick...
Disenchant: Kills a lot of annoying stuf

Orim's chant: Staple combo hoser.
Abeyance: see orim's chant but not so staple...
Enchantment's:Ghostly prison: stalls aggro
Seal of cleansing: see disenchant
Aura of silence: one sided sphere for shop decks.
Sorcery's:Tafiff: our answer to inkwell.
Armageddon: with sphere's and rider's around this could be pretty painful
Artifact's:
Chalice of the Void: seems obvious
Null Rod: See Chalice
AEther Vial: pretty nice when you're not running rod
Sword of fire and ice: ads to our clock and give's us card draw. Again, not whith null rod.
Thorn of amethyst: since we rely on our disruptive creature's to win, this thingy doesn't bother us all that much.
Pithing needle: pretty good all round.
Tormod's crypt/Relic of progenitus: standard ichorid hate (the latter one cantrip's buts cost's 2 to activate, and the first one's free)
Trinisphere: hose's combo more than any other
Crucible of worlds: when you like the waste/strip lock
Chrome mox: not to good with chalice and null rod, but maybe nice in a more stompy oriented style of deck.
Mox diamond: when you try to go like the legacy stax builds.
Possible lands:Plains (hidden secret tech for white decks)
Flagstone's of trokair: if we decide to run armageddon
Wasetland: fit's if you're going with mana denial
Strip^mine (wasteland nr 5)
Ancient tomb/City of traitor's: when you take the deck in a more (Angel)Stompy(/Stax) kind of way
Ok, so looks like mono white has the tools to be competitive since there are so many options (and I've probably forgotten a lot of those), it all come's down to Testing and feedback.
Decklist's will be up soon, but for now i would just like to see what OTHER'S can think of when trying to build a white (Weeny) deck.
Greetzzzz,
Robin.
