MTG Arena The Lost Caverns of Ixalan artwork for a cool-looking dinosaur

[Update #2]: MTG Arena's Alchemy: Ixalan mini-expansion is launching December 5th with some spicy new cards.

[Update]: The Lost Caverns of Ixalan has now arrived with dinosaurs, vampires, bonus Commander cards and a surprisingly aggressive limited format.

I hope you're in the mood for dinosaurs, vampires and weird fungus creatures, because The Lost Caverns of Ixalan expansion will be heading over to MTG Arena on November 14th. There will be 300 new cards to mess around with, a variety of returning mechanics like Explore, as well as three rather interesting new keywords: Craft, Descend and Discover.

To put it simply, Craft is a new way of transforming artifacts. By paying the craft cost and exiling a specific number and type of cards from the battlefield or graveyard, you can transform your artifact and get a powerful effect.

Descend is a mechanic that cares about permanent cards in the graveyard. This can be in the form of getting some sort of benefit when permanent cards hit your graveyard, or it could be an effect that cares about the total number of permanents in your graveyard. That said, it's important to once again emphasize that Descent only cares about permanent cards, so tokens going to the graveyard won't trigger your Descent abilities!

Discover is basically a fixed version of cascade. When Discovering X, you exile cards from the top of your library until you exile a card with mana value X or less, and then you can either cast it or simply put it into your hand. Afterwards you put the other exiled cards on the bottom of your library.

What all of these keywords look like on actual cards, as well as what each of the color pairings are going to be all about, that you can check out over at MTG website. If you're curious about the narrative and the characters behind both the cards and the expansion itself, you'll also be happy to hear there's an entire series of short stories to dig into!

The final thing worth mentioning is that MTG Arena will be getting a couple of Commander exclusive cards with The Lost Caverns of Ixalan. You can grab the four listed below by either playing with the preconstructed Commander decks in a WPN store, or simply craft them with wildcards.

Personally, I'm the most excited about Pantlaza because dinosaurs 'cascading' into more dinosaurs is almost guaranteed to be a good time! Anyway, the four bonus cards are:

 Admiral Brass, Unsinkable
Clavileño, First of the Blessed 
Pantlaza, Sun-Favored 
Xolatoyac, the Smiling Flood

Have fun brewing up new decks, and I'll make sure to let you know once The Lost Caverns of Ixalan goes live.
