Mono Red

Although it could probably use a little tuning and
some work on the sideboard, I think you'd be
hard-pressed to find a deck that can beat this.

4x Spark Elemental
4x Crimson Knight
4x Tribal Elite
4x Cyborg Replicant
4x Lightning Cat
3x Dragon of the Appocalypse
4x Static Electricity
4x Earth Flame
4x Electrocute
3x Swirling Fire
22x Mountains

S.B.
3x Crystal of Normalcy
3x Duplicate Chaos
3x Fracture
4x Kithsaran Runner
2x Eye of NoD

Spark Elemental - This guys a Jackal Pup with
basically no drawback in this deck save that you can't
play two at the same time. Probably the best T1 play
in the set.

Crimson Knight - First Striking Bear. Solid.

Tribal Elite - This guy is pretty savage. It is a 2cc
Stone Rain or a hasty bear. Excellent early-game
tempo card.

Cyborg Replicant - Colorless bear that will
occasionally be able to take advantage of
creature-type specific effects. Good for attacking
through pro-red.

Lightning Cat - Let's face it, except for some unusual
circumstance, this is basically a sorcery-speed
Lightning Blast. That being said, it is still one of
the more efficient burn spells in the set and is able
to deal effectively with annoying 4 toughness
creatures (of which there are a number in the set).
This might be replaced by one of the 4/4 goblins,
though (leaning toward the 2R one).

Dragon of the Appocalypse - 7/4 flier or Jokulhaps for
5 is not much of a choice for your opponent. Either
way you win.

Static Electricity - It's Lightning Bolt. If your
opponent is foolish enough to "swap" it back to you,
so much the better.

Earth Flame - Early/mid-game they are lands. mid-late
game they are Shocks.

Electrocute - Arc Lightning...sort-of.

Swirling Fire - What more can be said other than that
this is Fireball on crack.

The Sideboard --

Crystal of Normalcy -- the only rares in the deck (if
memory serves) are the Dragons. In certain matchups
it should pay to swap them out for Crystals.

Duplicate Chaos -- not completely sold on this, but it
seems to be a flexible answer for decks sporting
otherwise difficult to handle beasties (i.e. pro-red,
giant monsters, etc...). Uh, what happens when two of
these are in play on different creatures?

Fracture -- a nod to the artifacts in the set,
although it doesn't really seem that these would be
necessary. They could be sided in as poor Impulses
for matchups where you really need to get to a Dragon.

Kithsaran Runner -- I guess this is red's U/W-hoser a
little on the expensive side, though.

Eye of NoD -- For Elves and Merfolk? Maybe, though
they shouldn't really be a problem. May be better
served as a backup for creatures that are too big to
burn away (like Angels or Walls).

Another way to go might be to have the 4th Dragon and
4th Fire in the board.
