A Singleton Urborg, Tomb of Yawgmoth and Tolaria West would make Dismember easier to cast and give you another way to search out both Urborg and your Urza lands, or utility lands like Academy Ruins or Field of Ruin. It'll also make it easier to run black in your side board.

The life payment of dismember i've never found to be an issue with the 3 wurmcoils in the main. I'm already playing a singleton tolaria west, Transmuting to finish tron is great, or just getting a walking ballista.

Urborg might be hard to swing as any colored source in this deck really needs to be Blue, and 10 is a basically a minimum to function. my flex slot lands were field of ruin but I don't know think even trying to splash back would make the deck better.

Which your score playing this deck at fnm.

SwissRolls:

I saw your Mono-U Tron deck initially on MTG Salvation.

My Version: MDN Mono-U Tron

I have not played modern in approximately 6 months to 1 year. Over the course of 5 years of modern experience, I have played UW Flash (Circa 2014), Mono-Green Tron (Circa 2015), Merfolk (Circa 2016), Affinity (Between 2015-2017), Dredge (Early 2018), and Mono-Red Serum Powder Eldrazi Prison (Middle 2018).

I have learned to love hard control decks that say no for a certain amount of time and then turn the corner really hard once they have denied the opponent resources (mana/cards in hand), tempo (no tempo when everything is being killed and/or bounced back to the hand), card quality, and card impact.

I have never played Mono-U Tron in person yet, but it looks really fun. I have been following different iterations of the deck as far back as 2015.

Thank you for tuning and refining this deck. You work on refining this deck is very important to this underrepresented archetype. The big mana control deck archetype is traditionally difficult to tune to an open meta because it lacks the flexibility of the UWx control decks, and it stills has to find a way to turn really hard which leads to needing high impact colorless cards.

Do you have any advice on playing the deck?

sneex1 I pretty much always go 3-1, 4-0. I just recently went 4-1-1 at an MCQ.

Marcus_Licinius_Crassus Yeah this deck very much (especially in my build, and yours) plays the draw go game-plan. You need to analyze your opening hand a lot and decide what its doing: Do you know what your opponent is playing? Is this a tron hand or a control hand? this decides a lot of what you keep. In an unknown matchup I tend to favor the control hands. Having early interaction and trying to make it to turn 5-6 (normally when we assemble tron with a control hand). There is a lot of weird lines where a condescend for zero or repealing your own creature wins the game.

If an opponent is pathing a ballista I tend to use it to shoot down to 1 counter and then let the path resolve. The extra mana is normally very relevant.

I haven't personally tried 3 snapcasters but I can see their use. Its definitely a good card but double blue, triple blue can be difficult for our deck.

I really appreciate the kind words. I've worked pretty hard in trying to make this deck still playable in an ever changing, and higher power metagame.

Updated for post Oko, mox and lattice bans. My sb probably include more graveyard hate than one would expect but I have a feeling Dredge with the new ox and storm will be good in this new metagame.
