Where my Master Duel players at? I've been having, uh, not the best luck with it myself but damn is it fun to build decks in that game XD My mains ATM are Fish Linchro (currently nerfed due to ongoing bot shenanigans), Scrap Synchro and Adamancipators :o (I'd show off one of my builds but it's kinda hard to post screenshots on mobile lol)
(Edit: got onto desktop real quick to put this list here :P)
