4-color Junk

I have recently been molding a 4-color aggro/control/"junk" deck for a 10-proxy environment. Since I do not own Forces, Mana Drains, or any of the strong blue cards, blue is the color that is missing. Since there have been a lot of lists posted lately about 5-color "Fish" decks and BW aggro/control lists, I figure there are enough people thinking about the ideas of the decks that could possibly help me.

We have a smaller metagame, consisting of mostly other junk, Bob Tendrils, some not-fully-powered Workshops and Oath, Dredge, and some Legacy stuff that has been ported over (Merfolk, BWg Junk similar to B. Nelson's list, etc).

The idea for this deck was to have many answers in different colors and casting costs to handle different threats. Sphinx of the Steel Wind was a real killer for RG; shroud is a real killer for everything; Oath has the propensity to crush creature-based strategies.

Creaures:
1 Qasali Pridemage
2 Leonin Arbiter
4 Bob
1 Jotun Grunt
1 Aven Mindcensor
2 Gaddok Teeg
1 Goblin Welder
2 Magus of the Moon
1 Taurean Mauler

Sorceries and Instants:
3 Swords to Plowshares
1 Ancient Grudge
1 Nature's Claim
3 Thoughtseize
1 Duress
1 Extirpate
1 Serenity
1 Aura of Silence
1 Pernicious Deed
1 Darkblast
1 Crop Rotation
1 Diabolic Edict
1 Demonic Tutor
1 Vampiric Tutor
2 Lightning Bolt
1 Lightning Helix

Enchantments and Artifacts:
1 Fastbond
2 Crucible of Worlds
1 Zuran Orb
1 Elixir of Immortality

Mana:
1 Black Lotus
4 On-color Mox
1 Sol Ring
2 Marsh Flat
1 Windswept Heath
1 Bloodstained Mire
2 Swamp
2 Plains
1 Forest
1 Mountain
2 Scrubland
1 Taiga
1 Bojuka Bog

As you can see, it appears to be a "silver bullet" strategy. However, there is redundancy in the desired effects across different colors and different mana costs. I realize there are some odd choices, and I will explain a few of them.

Magus of the Moon: I run only one card with a double-color requirement of the same color (Aura of Silence), so I feel it is safe to run a few of each basic land and this guy. He really kills a lot of the strategies of opposing decks. Since I can operate under it with the basics I have (and the moxes, assuming no Null Rod), it is rarely an issue. And if there is ever a card I need, I generally have an option in another color.

Elixir of Immortality: Between the little fetches, Bob, and Thoughtseizes, having a little extra life was helpful. It also helps if I dredge down answers with Darkblast, or I need to get back a countered or played answer sitting in my graveyard.

There is an equal split of mana across the color requirements (if you exclude Bojuka Bog): there are 14 white and black costs in cards, and equal amount of mana or ways to find that mana across the deck; there are 8 green and red costs in cards, and equal amount of mana or ways to find that mana across the deck.

There is no sideboard, as that changes a lot, but imagine more of the maindeck in the sideboard, and there are 61 cards maindeck. I added Bojuka Bog as extra mana and dredge hate. Crop Rotation has served as a pretty good instant-speed graveyard hoser with the Bog, and I am not sure if I should really cut anything as it has not hindered the overall strategy.

Notable Exclusions: Since there is no real "focused" idea of the deck (mana denial, board control, etc.), I run no Strip Mine, Wasteland, or board sweepers (Balance). I am not sure if I need to. The deck is a lot of fun to play, but definitely not tier-1. It struggles in most game 1s, but it also has the ability to find an adequate answer to most threats without being too thin.
