>>33194638The last time I played this game before 2 months ago was Pokemon TCG for Gameboy and I'm already building competitive standard decks. Just play, the worst that'll happen is you'll lose games, but you don't really lose anything when you do. Pay attention to the threads, maybe watch some "beginner tips" stuff, you'll get the hang of it in no time.
Admittedly I also have 10+ years of MTG under my belt, but the games are somewhat different in how they're played.
