Where to find meta decks?

Hello! I am a MTG cast away (damn universes beyond). I just started playing this a week or so ago, dropped $100 on packs with the black friday sales so i got a ton of stuff, also just got done getting all 12 starter decks. Im just looking for the best place to find the meta decks, and to see what im missing so i can start grinding ranked! I was a midrange or agro player exclusively in MTG. So im super interested to see what a proper midrange deck in Kards plays like
