Ranked in these QuestionsQuestion Ranking
Pros
Pro Free-to-play friendly
You can trivially make a tier 1 competitive deck after completing the starter quests. There is no need to spend exorbitant amounts to remain competitive.
Pro Visually impressive
Lots of fun animations bring the game to life.
Pro Smooth experience
Lots of clever optimisations keep the pace of the game fast. For instance, if the game detects that you have no legal plays available in the current phase, it will auto-skip the phase (unless you stop it manually). This makes the game flow much faster than its clunky predecessor MTGO.
Pro Exciting, varied metagame
The "standard" format (the current format played in MTGA) is very healthy at the moment, with a diverse array of strategies seeing play at the highest levels.
Pro Interesting limited-time "event" modes
Various fun events such as singleton (no more than 1 copy of each card in your deck) or various content creator-designed modes keep the game fresh and interesting.
Cons
Con Pay to collect
Con Mana flood /mana screw
Sometimes you will have more mana then you know what to do with it. Sometimes you won't have enough.
