You can now play 'Magic the Gathering Arena' on iOS
In case you missed the news, Magic the Gathering Arena is now available on the iPhone and iPad. You're no longer limited to playing it on the Mac. And if you have an account there, you can use your previous account on your iOS devices. MTG Arena is a free-to-play game, but it does offer in-app purchases that include card packs, gems, and more.
