Sam has a cycle of early previews to show off to set the stage for the rest of Amonkhet!
This is huge. Fetchable cycling lands are insane. They come to you via search tech, and are amazing draw tech for decks that revolve around lands and discarding.
Off the top of my head this may give a price jump on Life From the Loam and some other tier 2 staples like Zombie Hunt and Seismic Assault jump in price.
This may also brief more life into Dredge after the re-banning of Grave Troll (RIP).
So, with this news. Buy low on these Modern tier 2 staples and sell high, or buy in big with Loam.
The bad brews in my head are already percolating. 5 Color seismic assault may be a thing now.
