Amonkhet continues to influence sales, but there's some modern stuff going on this week too. I'm going to just hop right in. It's Monday. Let's not delay the gratification any longer than we have to.
After Golgari Grave-Troll was banned in Modern, conventional wisdom stated that Dredge no longer had the power to be a contender. This is demonstrably false. Dredge has had to make a shift in the absence of Golgari Grave-Troll, but Life from the Loam has fueled many a ginormous Conflagrate in recent weeks.
I'm guessing Scrap Trawler sold well because it's a cheap, in-print piece of this badass deck:
This triumvirate of Modern Masters 2017 uncommons illustrate the limits of what you can do with one mana of each color in the format. The latter two are highly efficient one-for-one trades, while the latter offers the best card selection on blue can get you in Modern.
#mtgfinance culture has come to this: A new set with the cycling mechanic, Amonkhet, is announced. Stores bump the prices of their copies of Fluctuator, lest they get burned by speculators trying to make a quick buck. However, stores are dealing with the least-deterrable sub-community Magic has to offer. #mtgfinanciers start buying out Fluctuator's inverse, a card from Scourge called Stabilizer. The card did nothing while it was Standard-legal and will continue to do nothing forever, but things like "facts" and "reality" have never stopped anyone from speculating on wizard squares.
Is Aether Hub the best card in Kaladesh? Absolutely not. Kaladesh is a busted set from top to bottom. The power level of some of the individual cards is ludicrous. Smuggler's Copter and Aetherworks Marvel are the tip of the iceberg. However, there is no doubt that Aether Hub will be the best-selling Kaladesh card before the set rotates out of Standard, and it won't be remotely close. As Standard gets more bloated, decks will cheat on mana in more ways. This can already be seen in the Four-Color Copy Cat decks that employ four copies of Attune with Aether in exchange for the ability to play fewer lands. Attune with Aether is a game-changer, and Aether Hub plays well with it.
If Aether Hub is the best-selling card from Kaladesh, then Fatal Push, another uncommon that simulatenously highlights one of its set's featured mechanics while pushing the boundaries of what an uncommon should be capable of, will be the marquee card of Aether Revolt. As much of a stranglehold as Heart of Kiran appears to have on Standard, it's never going to see play in Modern. What will see play in Modern, in steadily growing supply, is Fatal Push. In a format all about efficient threats, Fatal Push punishes this tendency without sacrificing raw power. There aren't many creatures that see regular play in Modern that can stand up to a fetchland plus a Fatal Push.
A common cycle of cycling Amonkhet lands hasn't been previewed yet, but many players seem to think a reprint of the common cycling land cycle from Onslaught is a foregone conclusion. That cycle of lands, along with the rare cycling lands, play well with The Gitrog Monster.
Splendid Reclamation is another card that plays well with cycling lands, but at a much more spec-friendly price point. I'm not convinced that it will actually accomplish anything in Amonkhet Standard and beyond, but it's fun to dream, and at the very least, is a solid short-term spec, given you're planning on dumping them before people realize the card is ineffective.
