With it's sideboard, this deck can be a very diverse mix of Aggro, Control and Combo all in one 75 card package.
1) It's primary focus is quick aggro. 20 life can be taken as early as turn 3 if you get the perfect hand, but lets be realistic and just say that turn 4 will happen much more consistently and the odds just get better from there on out. If you get overwhelmed, just sit back and defend until you are ready to strike.
Ex:
--------------------------------------------------------------------------------------
Typical Hand: Memnite, Ornithopter, Steel Overseer, Mox Opal, Grand Architect, Island, Contested Warzone.
Turn 1: Play Contested Warzone. Memnite, Ornithopter and Mox Opal for free. Cast into Steel Overseer.
Turn 2: Draw Darkslick Shores. Play Darkslick Shores. Cast Grand Architect. Tap Overseer for +1/+1 counters. Attack with Memnite, Ornithopter *3 damage*
Turn 3: Draw Signal Pest. Play Island. Cast signal Pest with Warzone. Grand Architect uses 2 blue to buff Ornithopter and memnite +1/+1 each, tap Overseer to give another +1/+1 each. Attack with Ornithopter and Memnite. * That makes 7 more damage, they're half dead!*
Turn 4: Draw: Tezzeret, Agent of Bolas. Play Tezzy, -1 to make Signal Pest a 5/5 and attack with everything.
That's 3 from the Ornithopter, 4 from the Memnite. 5 from the Signal Pest and 5 from the Steel Overseer this turn. 4th turn damage total, 27!
--------------------------------------------------------------------------------------
Memnites, Ornithopters and Signal Pests make it easy to throw down some creatures on your first turn and start bashing away. What gets better, is when you play a Steel Overseer and start pumping up your cheap creatures. However, the key to this strategy is the Grand Architect. All those little creatures can become huge mana producers and/or become blue for the temporary +1/+1 buff.
2) It's secondary focus is combo, (well sort of). With Tezzeret, Agent of Bolas, the ENTIRE deck is a combo all in itself. There isn't much else to say about it. It is what it is and it works great! Obviously, the Trinket and Treasure Mage package make it even easier to grab those important pieces to your doomsday machine, especially that contagion engine. That beast will usually end the game if you get it out with Tezz on the board. Not only that, with the right cards down, you can have your 6 casting cost cards in play by turn 3-4 consistently with help from Everflowing Chalice and Grand Architect.
3) Control. Knowledge Pool will be hell for Valakut or Control deck players of all sorts.
"Hmm.. oh, so you want to counterspell my Tezzy huh? Nope! put it in the pool and cast something else punk!"
Oohh.. you wana cast harrow? Primeval titan? Green sun's zenith!? Day of Judgment? Nope sorry. In the pool with you!"
The greatest part of all of this is the fact that you can side in more JaceTMS, cast Knowledge pool and FIX what top 3 cards are exiled from your end. that way, you can give them a useless memnite, while you in turn cast, say, their Grave Titan. ABSOLUTELY FREE!
Of course the Pool does have it's drawbacks. You can't counter anything either, but that's why the main deck doesn't have many counters or removal spells. If you get the pool out, you don't give them many worthy options for their decks to use.
4) The sideboard. It's teeming with things to make sure your opponents are locked down. Comes complete with a removal package in the form of 2 Doom Blade, 2 Go for the Throat, 1 Ratchet Bomb and 2 Black Sun's Zenith.
Board wipe and the need to Wipe the board:
The Wurmcoil Engine, Mimic Vat, Ratchet Bomb, and Black Sun's Zenith are there in case your creatures get wiped so you can retaliate. For aggro decks that are faster than yours, you can hold off casting anything and use one of your wipe spells, then play all your goodies on turn 2-3.
The Zenith actually works rather well in this deck if you happen to keep a Steel Overseer on the board for a few turns, and even more so with the help of the Contagion Engine.
Against the UNbeatable:
Memoricide will obviously help you get rid of those pesky cards that you don't want to be used to kill you again if you lose your first game, such as pyroclasm or Day of Judgment. Board sweeping cards early on are the most dangerous to this deck, just like any Aggro deck. Also, your Creeping Tar Pits are hungry for some hoodie wearing blue mind mage and his planeswalking buddies!
