Again, It creates absurd amounts of mana, but can only do it by finding very specific pieces, which stops working if broken up. Seriously it's not complicated to understand that it's very easily interpreted this way.
Frankly I personally feel like NOT counting tron as combo is really ignorant, as you are ignoring things that I feel are clearly apparent in the nature of how the deck operates. Digging, filtering, tutoring trying to safely and quickly assemble tron to play spells well out of the typical price range and reasonably hold a certain amount of inevitability that fair decks simply can't rival. Yet, I haven't specifically come out to say that you are the wrong one here, i've just let it be known that I feel like tron IS combo and this is why so when I point out that the top 8 really DOES feel super combo heavy people understand where i'm coming from.
Don't think of it as mana acceleration then; what Tron is doing by fetching the specific pieces is 'color fixing' so to speak.
Imagine if Wurmcoil Engine's mana cost was :sym2w::sym2u::sym2b:. Assembling a Plains, Island and Swamp (without the assistance of fetches or duals) would simply be a hoop that the deck is jumping through to drop an undercosted threat.
Semifinals
Anteri (RG Tron) vs. Bjorklund (Living End)
Sotiriadi (Jund) vs. Dickmann (Twin)
Jund should take the Twin matchup without much difficulty, and Tron should take Living End down pretty handily. That would leave a Jund/RG Tron finals which should hopefully go to RG Tron for the coolest GP Finish in over a year.
Other way around - Twin is playing Living End, while Jund is up against RG Tron.

Too many distinct angles of attack for a traditional control deck to thrive.
Isn't that what a control deck does? Weather the initial flood of threats, and then drop a win condition?
How do you explain cards like Pyroclasm, Oblivion Stone, Karn Liberated and All Is Dust?
