What's the best Android app for learning to play Magic: The Gathering digitally?

Magic: The Gathering Arena is a comprehensive digital adaptation of the classic card game, specifically designed to onboard new players. The app's primary strength for learners is its multi-part color challenge tutorial, which systematically introduces core mechanics like mana, summoning, and combat. After the basics, new accounts receive several pre-constructed decks, allowing for immediate play in unranked matches or against AI-controlled Sparky bot to build confidence without pressure. The game also features a robust economy where players can earn new cards and decks simply by playing daily, reducing the initial financial barrier to building a collection. However, the learning curve remains steep due to the game's inherent complexity, and some user reviews indicate the mobile version can suffer from performance issues like crashes or long download times after updates, which can disrupt the learning flow. For those willing to persevere, it provides an authentic and mostly accessible entry point to the world of Magic.
