Our first "Epilogue" set, interesting. I like the idea of a set taking place across multiple planes (March of the Machine), curious to see how they'll make that cohesive. The Origins/Urza's block approach wasn't terrible, but I think would be too limiting here.
Eldraine is pretty exciting, that set had an excellent aesthetic and I'd kill for more adventure cards. The promise of Ixalan was always much, much better than its execution, so maybe we can get more Mesoamericans, pirates, dinos, and conquistadors that redeem the original block much how like Theros: Beyond Death made the original (very boring) Theros feel like a plane worth returning to. Ixalan has some of the most wasted potential around, I hope they don't go too hard on the spelunking stuff.
