There's a lot of strategic depth to Magic or MTG. There is usually a pretty good variety of top-tier decks you can play. From my perspective, you can generally find a tier that fits your playstyle or color preference and is still competitive.
Do you believe that games can relieve stress levels?
So, I choice play mtg to do that.
The cool thing is, if you stop playing for a year or four, it's not like your deck becomes obsolete. If you were playing standard, you could switch to modern legacy, and that's that.
