Here are my Deck Profile which i use on Duel Master 2022 now. I would say this is not perfect build, but i can running smoothly to bring you up to Platinum level.
The deck is simple, not to much combos. You can play this deck even you're beginner.
Gravekeeper is good to lock down the graveyard and special summon engine for your enemies.
Any suggestions are appreciated! Thank you, have a nice day.
