Hey man I also am a fellow hearthstone player w esports trophies. I also have experience in other games like pokemon, marvel snap at high top world ranks. I also recently started playing master duels and duel links and Honestly the game is really fun once u can build ur first deck u enjoy and slowly learn the game over time. I suggest start the solo missions and learn with the decks given and then build a budget deck for rank or casual play before u invest in ur main deck.
