Amazingly helpful!
As someone who has only been playing Magic for a few weeks with little to no prior knowledge of how to play, this app has been extremely helpful to me. From the quickly-accessed glossary to the news updates, the timer to the counter of poison counters, this app is extremely useful. However, I would recommend that both you and your friend have this app, because it only keeps track of ONE person's life... But this shouldn't be an issue, as it is a free app. :) 5/5!
