This is a take on U/w Tron with a splash of the Trading Post engine with the Mindslaver win condition.
Lands: 23
4 Urza's Tower
4 Urza's Power Plant
4 Urza's Mine
- These should be obvious as to why they are in here. They accelerate into crazy amounts of many to cast stuff like Karn and Wurmcoil Engine
2 Celestial Colonnade
-The mana this deck can produce is crazy high and Colonnade just gives the deck another way to apply pressure.
2 Academy Ruins
-This land is one of the best ways to win the game through Mindslaver lock or it can be used to keep reusing Wurmcoil Engines and Expedition Maps.
2 Tectonic Edge
-Tectonic Edge is not only a strong card, it can be a defensive card as well against Sowing Salt.
3 Islands
2 Plains
-The high number of basic lands in this deck is related to the 2 Solemn Simulacrums.
Creatures: 9
3 Wurmcoil Engine
-One of the best Artifact Creatures in Modern and it just gets better with the addition of Trading Post and Academy Ruins
2 Solemn Simulacrum
-This 4 mana 2/2 does a lot more work than you think. The combination of this card and Trading Post is crazy.
1 Snapcaster Mage
-Just a generically good creature to help abuse the graveyard in necessary situations.
1 Treasure Mage
-A 3 drop tutor for Wurmcoil Engine, Sundering Titan, and Mindslaver, 2 of our stronger win conditions. Once it's on field, it makes for a good chump blocker or Trading Post fodder.
1 Sundering Titan
-Another big old win condition that can be abused with Trading Post and Academy Ruins.
Planeswalkers: 2
2 Karn Liberated
-Unchecked, Karn can take over a game on his own. It is just an additional bonus that he can be a turn 3 drop.
Artifacts: 13
4 Expedition Map
-This is one of the best ways to accelerate into Tron as it works well with a turn 1 tron land and a turn 2 different tron land.
2 Azorius Signet
-Another way for this deck to produce Blue and White mana from the Tron lands
4 Ichor Wellspring
-An artifact that draws cards is good. This is a mainstay with Trading post as it can be a 3 mana draw 3 combo.
3 Trading Post
-This is my favorite card in the deck. It's synergies with Wurmcoil Engine, Solemn Simulacrum, Ichor Wellspring, and Mindslaver are crazy good. It allows you to draw cards and recur artifacts each turn. The life gain and goat tokens are also useful against those aggressive decks if needed.
1 Mindslaver
-Who doesn't love a game winning lock?
Instants and Sorceries: 13
3 Path to Exile
-The white in this deck gives it access to one of the strongest removal spells in Modern.
3 Condescend
-A simple counterspell that gives a scry 2 effect. Most decks won't be able to pay for the X with the amount of mana the Tron lands can produce.
2 Thirst for Knowledge
-Another draw card in the deck. Most blue based Tron decks run 3-4 copies, I think two is fine especially since we also run...
2 Sphinx's Revelation
-Lots of mana fast? Check.
Lots of life gain? Check.
Lots of cards drawn? Check,
It all checks out.
2 Repeal
-With all the mana the deck can produce, Repeal can almost bounce anything.
1 Spell Burst
-This can possibly be a continuous counter spell with it's buyback ability.
