I'd replace Artful Dodge for Distortion Strike .

I love it. Reckless charge is an old favourite of mine.,+1

An Idea I was pondering the other day was a way to incorporate black into a deck like this and run Tainted Strike .

Brute Force + Kiln Fiend + Tainted Strike is game over.

But getting that third colour in could be difficult and end up not really being worth it.

Assault Strobe + Kiln Fiend + Tainted Strike works as well.

Tainted Strike look really good, but i am afraid of third color. In non-pauper format is possible to use Crumbling Necropolis , but here i stay in two-color deck. Anyway really thanks HumanOverlord for your valuable suggestions. :)

I have no idea if it would help, but t1 win is possible as well with this type of deck.

T1: Mountain, exile Simian Spirit Guide x2, play kiln fiend, Lotus Petal , play reckless charge and either Tainted Strike or Assault Strobe .

Whoever said pauper is underpowered?

Great deck!

My preference over Peek is Gitaxian Probe but if your just looking for filler then I think the best card is Street Wraith (who is common in the Modern Masters expansion).

Maybe Mutagenic Growth ?

I don't think I would bother with Counterspell. Double blue is risky in a two-colour pauper deck, and you should be able to just outrace anything worth countering. Have you considered Shadow Rift ? It's card-drawing and evasion in one.

I feel like half the decks on this site are DelverFiend decks. Here is the most recent collection of lists I could find:

Delver of Secrets  ^Flip over Wee Dragonauts

Gitaxian Probe over Peek any day.

Titan's Strength over Brute Force for the Scry.

Artful Dodge over Distortion Strike Because you can cast it twice in one turn.

Brainstorm over Lightning Bolt

Drop the guild gates and run basic lands, never want to draw into a stupid guild gate.

Other Colour Phyrexian Cards:

Mutagenic Growth

Apostle's Blessing

Hope this helps.

Have you considered Young Pyromancer it might be good for defending agains other fast decks. Because while you are powering up your creatures Young Pyromancer is spitting out tokens that can defend you.

Instead of Assault Strobe how about Armed ?they do the same thing but Armed gives you an extra +1+1 buff.

I'd drop 4x Ponder and add 4x Shadow Rift for more unblockable and still a cantrip. I'd also drop 4x Counterspell and add 4x Mizzium Skin . The only time you'll want to counter something is if its going to kill your creature, so 99% of the time Mizzium Skin will work much better and is much easier to play. Other than that, this deck looks like a lot of fun!

Also, I do agree that Titan's Strength is much better than Brute Force .

instead of Peak you should be running Gitaxian Probe , its a much better card for the fact that it can be payed with 2 life instead of needing the blue mana, and had the same effect.

sorry i ment Peek

I would agree with the recommendations to play both Gitaxian Probe (I would reccomend playing 4 of them) and Shadow Rift. Both cards are amazingly powerful in this deck.

I recommend switching the two Izzet Guildgate 's with two Swiftwater Cliffs .

Hey you inspired me to create my own deck, using some of the idea from here why don't you check it out :)

Hope to see you on MTGO.

Apostle's Blessing is usually a must in this deck for the extra unblockable/pro removal and i found that i liked Artful Dodge more than Distortion Strike because i could fire it off two times in one turn if i had 2 island and 1 mountain. Since double striking is usually required for the kill Artful Dodge makes it to 10 power when Distortion Strike can't
