Master Transmuter is one of the most powerful creatures in Extended. Unfortunately, Faeries has prevented this deck from achieving competitiveness. Mirrodin Besieged does a good job of changing that, though. Faerie decks will, and I say this with almost 100% certainty, play Go for the Throat as their removal spell of choice. To them, Go for the Throat is a strict upgrade to Doom Blade. Cards like Putrid Leech, Demigod of Revenge, and Doran, the Siege Tower are all of higher priority than cards like Master Transmuter and Platinum Emperion to any tournament savvy player.
This minor change in the outline of Faeries gives us an opportunity to capitalize on the potential power of Master Transmuter and its friends. That's not the only trick we've picked up to fight the Faerie Menace. Shimmer Myr gives us an opportunity to resolve our spells or force an unwilling Faerie player to fight with countermagic on their own turn.
Spine of Ish Sah may seem expensive, but once you get this thing going with a Master Transmuter, you will understand why it's worth the wait. Destroying one or more permanents every turn is backbreaking for any opponent.
Treasure Mage may seem gimmicky, but it's kind of like a really bad Sphinx Summoner. Treasure Mage combos nicely with Grand Architect to put some very scary things on the table at very early turns of the game.
I experimented with Grand Architect in the past and it seemed like a necessary tool if I were planning on using cards like Spine of Ish Sah and Shimmer Myr. It's worth noting how strong the pump ability on this creature can be. It makes your Master Transmuter dodge things like Disfigure and double Cunning Sparkmage. It makes your Trinket Mages, Treasure Mages, Etherium Sculptors, and Sphinx Summoners all into serious beaters.
Trinket Mage is a nice addition to have when you're playing Grand Architect. Most of the time, you just grab an Everflowing Chalice to help your mana situation, but there are a lot of situations where a Chimeric Mass or Executioner's Capsule can really put a damper on your opponent's plans. Elixir of Immortality is strong against red decks and it lets us shuffle our graveyard back into our library if we've already used Sharuum the Hegemon and need to get a Sphinx Summoner going.
Etherium Sculptor is the deck's turn two play of choice. In fact, I've found that I rarely lose a game when I untap with an Etherium Sculptor on the battlefield. It's especially powerful when combined with Grand Architect. The cost reduction alongside the mana ability allows you to get things like Spine Ish Sah into action a lot faster than one might expect.
Shimmer Myr may shine the brightest when you're playing against Faeries, but it's worth noting how powerful it can be against other decks. Flashing in a large artifact after your opponent makes his attack can often be the advantage you need to win the game.
The top-end package is completely ridiculous:
Wurmcoil Engine is a necessary top-end spell that the deck needs to have access to as a turn four play. Decks like Jund and Mono Red can run you over if you don't have access to a single copy of this card.
Sphere of the Suns is like a bad Everflowing Chalice. That being said, it's still quite good. This deck desperately wanted more two-drops that helped lubricate the avalanche of card advantage and board position that starts around turn four or five.
Thousand-Year Elixir is incredible with Master Transmuter. I found myself losing most games where I drew more than one copy, though. I decided the only way to guarantee I wouldn't draw more than one was to only play a single copy. If you decide to play cards like Scarecrone, then you probably want a few extra copies of this in your main deck.
A lot of readers suggested that I use Mindlock Orb in my sideboard to help against the Valakut, the Molten Pinnacle decks. While the effect is powerful, I'd rather not turn off my Sphinx Summoners and Mages. Leyline of Sanctity seems like a much better choice.
I definitely want access to a Sphinx of the Steel Wind post-board to soften up our Jund opponents.
Lodestone Golem can make things really difficult for players that rely heavily on a specific curve. Playing a full four of these post-board can often make things very difficult for opponents. Remember, Lodestone Golem is especially strong in multiples. With the help of Sphinx Summoner and Master Transmuter it's reasonable to assume we should have trouble finding a few copies in the same game.
The rest of the sideboard is designed to help us tune the deck for specific matchups. This sideboard configuration allows you to shape your deck based on what cards you've seen from your opponent.
Here's the final 75:
I played a few matches with the new list to see how it would fare against the latest versions of decks like Faeries. Match reports are particularly enlightening to read with a deck like this. Understanding the unique interactions between different spells is very important.
Note: The Faeries deck my friend and I used has four copies of Go for the Throat and two disfigures.

Go for the Throat may seem like it makes Faeries better than ever, but it certainly gives this deck a huge advantage. Shimmer Myr and Spine of Ish Sah give this deck the tools it needs to compete in the latest version of Extended. I strongly recommend putting this deck together. It's one of the most fun archetypes you can possibly play with.
