[Update #2]: Magic: The Gathering is extending its Standard rotation from two to three years in order to help the floundering format on tabletop.
[Update]: MTG Arena's March of the Machine expansion has now arrived with a new card type, improved duplicate protection, and the ability to select your favorite card style!
I hope you're not feeling overwhelmed by the constant influx of new cards, because even though Shadows Over Innistrad Remastered has only just arrived, the MTG Arena team is now getting ready to unleash a rather massive Standard expansion. Not only that, but once the March of the Machine set arrives this April 18th it'll do so alongside an entirely new card type - Battle!
Each Battle enters play with a certain number of counters on it, sort of like a Planeswalker card. In order to unlock the special (and often quite powerful) effects found on the flip side of each Battle you'll need to reduce those counters to zero by either attacking said Battle or by using certain types of spells to damage it or remove its counters. Notably, destroying Battles directly will not flip them - you need to remove all of the counters 'fairly' to get to the goodies!
Since trying to explain Battles through words alone is a bit tricky, allow me to share with you one example. It should hopefully give you a pretty good impression of what Battles look like on the front side:
If that little teaser has piqued your curiosity, you'll be happy to hear that the entirety of the March of the Machine set has now been unveiled. You can find the full list of cards, all neatly sorted by color, over at the official website.
There is, however, one more thing to mention, and that would be the Multiverse Legends cards. Much like Strixhaven's Mystical Archives or Brother's War's Retro Artifacts, a single common in each March of the Machine pack will be replaced with a popular legendary creature from previous sets. So if you're a fan of Commander of Historic Brawl formats, March of the Machine should be quite a treat. You can find the full list of legendary creatures, and this also includes the all-powerful monkey Ragavan, over at the Multiverse Legends card gallery.
Once the March of the Machine set goes live, I'll make sure to let you know. Until then, I'll leave you with the overly dramatic cinematic trailer. Enjoy!
