I'll admit I'm not much of a Valakut, the Molten Pinnacle player. The decks it's in tend to be pretty straightforward, and the strategy is just so inelegant I have a hard time enjoying it.
But if it's the price I have to pay to put Unexpected Results and Emrakul, the Aeons Torn into my deck, that's a price I'm a willing to pay.
Yes, this deck has a Valakut plan attached to it. Once you decide to ramp without using Tron, it's hard not to land (heh) on some sort of Mountain-equals-Bolt strategy. We can play ramp spell into ramp spell into Primeval Titan and kill people from arbitrarily large amounts of life.
But we can also cast Eldrazi off of Unexpected Results. I know which I'll be trying to do.
In all honesty, this direction for the deck actually makes some sense. The deck has toyed around with Through the Breach and Emrakul, the Aeons Torn before, and this is just another way to cheat them into play—actually cast them—which means payoffs like taking an extra turn. And, of course, with Valakut, the Molten Pinnacle even the worst-case of hitting a land with Unexpected Results is actually still a positive. It's a neat deckbuilding trick that does make me like the deck more.
The sideboard is spicy as well. Madcap Experiment and Platinum Emperion? That's a combo that some decks just simply cannot beat. It buys you all the time you need to grind them out with Valakut, the Molten Pinnacle, and the rest of the sideboard is tailored to individual matchups.
I'm not sure if this is a better or worse take than the traditional Red-Green Valakut decks, but I do know it gives it an angle of attack that the other build lacks. In a world of powerful sideboard cards like Alpine Moon, Field of Ruin and Blood Moon, the Valakut, the Molten Pinnacle plan isn't as reliable as we'd like and the backup plan of attacking with Primeval Titan lacked much an impact when the trigger was essentially meaningless. Now, however, every land you fetch might be "meaningless" in terms of Valakut, the Molten Pinnacle but extremely meaningful in terms of casting Ulamog, the Infinite Gyre or Ugin, the Spirit Dragon.
If nothing else, it makes this the most enjoyable version of Valakut I've come across, and I could see myself actually sleeving this up for a big tournament.
