Tron decks in Modern have been popular for quite some time, as producing more mana than the opponent and casting more impactful spells is always a recipe for success. In recent times, these decks have been moving more towards Eldrazi Tron, as that deck provides more midrange threats and can close games out quickly. However, traditional Tron decks have been making a comeback thanks to metagame shifts, and the list we’re featuring today is evidence of that.

Like all Tron decks, this deck is very interested in getting the combination of Urza’s Tower, Urza’s Mine, and Urza’s Power Plant into play. This deck is heavily reliant on getting its big mana into play, so it needs to play some efficient ways of searching out these lands. In this deck, that’s found in Expedition Map, Sylvan Scrying, and to a lesser extent Ancient Stirrings. The first two cards immediately search out any missing piece of the puzzle, while the latter doesn’t guarantee that you find what you need, but is a powerful late game threat nonetheless.

Once the big mana is in play, this deck has a number of ways of pulling massively ahead of its opponents. Karn Liberated is perhaps the most efficient of these, as it only requires that the 3 Tron lands are in play before it starts aggressively blowing up the opponent’s permanents and putting a chokehold on their hand. Wurmcoil Engine is another good way of stabilizing a board, as it’s very hard to attack into for many decks and blanks much of the removal found in this format. Ulamog, the Ceaseless Hunger is a powerful, game-ending card that can singlehandedly swing the game in Tron’s favor, while Walking Ballista is a really nice curve-filler that can be impactful whenever cast, as well as a nice mana sink in the late game.

Because this deck doesn’t quite hit the ground running in most games, it’s heavily reliant on ways of limiting the opponent’s board progression or outright destroying their side of the field. Ugin, the Spirit Dragon is an excellent way of doing this, as it cleanly answers almost all permanents in the format, while providing a planeswalker that has the ability to end the game on its own if given enough time. Oblivion Stone is another powerful board wipe that takes advantage both of this deck’s high mana production as well as its tendency to not have a ton committed to the board in the early turns.

Here are the changes I would make going forward:


-1 Oblivion Stone

+1 World Breaker


-2 Leyline of Sanctity

+2 Warping Wail

This is day 344 of’s 2017 Deck of the Day column, where each day we’ll feature a different Standard, Modern, or Legacy deck that caught our eye. You can read day 343 here, where we featured a Legacy Stoneblade deck that takes the archetype to a somewhat untraditional color combination.
