Get to the Choppa!
Arnold Schwarzenegger, known for his time travelling ability, already tried to tell us that in Predator (1987).
The airforce has arrived
I told you that we would see a flood of aggressive Copter decks in week one, but it seems even I underestimated both the omnipresence of the card, and the unpreparedness of the market. When the price spiked the first time after my suggestion, and more and more articles praising the Copter started popping up, I thought that most players had received the message before the weekend already. It seems like many still wanted to see tournament results first, and they ended up paying for it. The results of the SCG Standard Open were unambiguous: 32 copies in the top8, depite featuring at least 4 different archetypes (or more if you differentiate between the various W/R decks).
Copter is going to be one of the format defining cards. Players will stop using removal that doesn't kill it. Planeswalkers and control decks in general will have a hard time moving forward, but not all hope is lost yet. Aggressive decks win the first Standard tournament of the season all the time.
So what should you do now? First of all, you should start selling your additional Smuggler's Copters. The cat is out of the bag now, and even if there would be 32 copies in the Pro Tour Top8 as well, there should not be another big spike. By now everybody already knows that they will need a playset of this card if they want to play Standard. Kaladesh will be drafted and redeemed for 6 months, putting continuous pressure on the price in the long run. There is no way a rare card can stay above 10 € for a long time in a beloved first set of a block with Masterpieces, even if it is the best card and colorless.
I would also sell most planeswalkers, especially the ones that are expensive at the moment, like Chandra, Torch of Defiance and Liliana, the Last Hope. These girls will be hit by cars and airships badly. They will go down over and over again on the battlefield, and soon enough their prices will go down as well. Get out while you can.
What if I don't like Choppas?
Are there any cards you should look to pick up besides whatever you want to play?
I still like
Skysovereign, Consul Flagship From(EX+): 4,25 € Price trend: 4,44 €
It was used as a 2-of in the winning deck and in similar copies. If this becomes the trend, then the price should go up. It is twice as rare as Copter and needed half as often. You can do the math.
The other card that could be a complete bust, but I think it has enough potential to be an interesting pick up, is
Aetherworks Marvel From(EX+): 3,30 € Price trend: 3,53 €
It will get additional support in the next set - Aether Revolt, but it seems like it already can put up a fight. Daniel Weiser finished 25th with an early version of the combo shell I expected to see it in. The point here is that it might be difficult to play control decks, and combo decks may be the answer to a format filled with cheap creatures and vehicles instead. If that were true, a variant of the following deck could become the break-out deck of the Pro Tour, sending the price of the marvelous Aetherworks through the roof.
