You probably want to keep your deck unique but Karn Liberated would be great here maybe as a 2-3 of.

Extensive testing by the whole Tron community agrees that Karn Liberated is underwhelming in U Tron. Karn is a bomb early in RG Tron, but U Tron is not a racing deck, the point is tempo controlling your opponent, and by the time you get tron up and running, they're too thinned out to be able to deal with your wincons. Whereas RG Tron cares little to none about interacting and focuses and racing to drop a turn three Karn to shut down the game. The decks share a ramp method, but play fundamentally differently.

That said, Karn is an awesome dude. The backbone of bigger brother RG Tron.

Instead of Trickbind, I suggest Squelch. It is great for turn 2 stopping an opponent's Fetchland and can win you the game right there.

Trickbinds does the same thing does it not? In split second no less.

Squelch cantrips which is, IMO, better than Split Second.

That, is true. I'll probably switch the trickbind and switch out a dismember for a second one as soon as I get my hands on some. It turns out I had grossly underestimated the usefulness of countering activated abilities.

I usually side out Remand for Squelch when it's needed, which works out due to them both drawing a card meaning you lose zero tempo and get an appropriate counter for the match.

As much as I hate saying this as a bogle player, Spellskite is perfect in the sideboard. Bogle cannot win a game if you land this guy.

I know. I want to put it in the sideboard, I just have no clue what to drop for it.

-2 Ratchet Bomb for +2 Spellskite and -1 Trickbind, -1 Dismember for +2 Squelch. You are packing a little too much aggro disruption and I think it takes away from your disruption against other match-ups. 3 Dismember is too many, especially if you consider that each one (without Urborg)is costing you 4 life. Ratchet Bomb I have found too be slow against everything except tokens(tokens are really only Tier 2, so if your LGS has some then I could see keeping it) and Spellskite can block a lot of early threats slowing aggro down.

Edit on my above post: I just read your above match review, I would replace the Echoing Truth then with Spellskite. They don't target boggles and Affinity can just recast everything, and tokens can flashback Lingering Souls.

True, I just keptvechoing truth to have something I can use if my opponent resolves a stony silence post board. I guess I should just be a good player instead and hold up a counterspell for it :)

And I will be taking the advice for the squelches as soon as I get my hands on some. Thanks for the detailed input. Much appreciated.
