This past week might end up being the least exciting and least active for MTG finance so far in 2015. We're in the doldrums of summer, BFZ spoilers are still a week away from really starting (with a Pax Panel next Saturday night at 7:30 EST), and the most important tournaments of the weekened are Legacy and Vintage, which I love to watch, but don't typically drive financial markets. This adds up for a slow week, but don't worry &emdash; things will be picking up shortly and we'll be back to business as usual.

Evolutionary Elves

The biggest news this week is Evolutionary Leap (up 14 percent in the last day to $2.38) and Cloudstone Curio (up 211 percent to $17.99) which shot up in response to CVM and friends "breaking the Modern format" with a turn two combo Elves deck. While Cloudstone Curio has been comboing off in various Elves build for years now, the big improvement in this build is Evolutionary Leap as a combo piece. If you're familiar with Legacy Elves, you'll know the main way the deck generates infinite (or nearly infinite) mana is by combining Heritage Druid with Nettle Sentinel. The problem is you need to keep drawing and casting more Elves to keep this chain unbroken. In Legacy, this is typically done with the banned-in-Modern Glimpse of Nature (as well as Wirewood Symbiote). CVM and friends figured out that Evolutionary Leap combined with a bunch of one-mana Elves can do a pretty good Glimpse of Nature impression. You play an Elf, untap two Nettle Sentinels, make three green mana with Heritage Druid, sac the elf you just played to Evolutionary Leap, get another cheap Elf, rinse and repeat. Since each Heritage Druid activation adds three mana, and activating Evolutionary Leap plus casting an one mana Elf only costs two, you actually net one mana through this process. Eventually you generate 15 mana and your Evolutionary Leap hits your one-of Emrakul, the Aeons Torn and boom &emdash; you have a turn two Emrakul.

Evolutionary Elves

Whether or not this Elves build is really format breaking remains to be seen, but people are going to build it because hardcasting Emrakul on turn two is just too much for people to resist. The downside of Evolutionary Leap in the long term is that it seems unlikely to have as wide of an appeal as Collected Company. Where as CoCo is good enough for Modern just by grabbing random value creatures and adding eight power to the board at instant speed, Evolutionary Leap seems tricky to use as a value card which might limit its appeal and price.

Movers and Shakers

In other news, Anger of the Gods ticked up 15 percent while Temple of Epiphany dropped 25 percent. Both cards are rotating from Standard in a little over a month, but Anger of the Gods appears to have more Modern potential at the moment. Magic Origins is continuing its steady decline as supply increases. While these are small changes, underplayed mythics are losing between 5 and 10 percent per week which adds up to significant losses in the long run. MTGO redemption of Magic Origins starts on Wednesday and the supply of the set will only increase further as redemption is a pretty good deal at the moment. The current retail price of a complete paper set of Magic Origins is just under $300, while you can redeem a set from Magic Online for about $125. In fact, the six walkers (five flip and one Hangarback) retail for more than it costs to redeem the complete set. If you were thinking of buying playsets of these cards for your Standard collection, I would definitely encourage you to check out redemption.
