First, you gotta update some of the cards.
Harpie’s, pot of greed. All out, they’re forbbiden
Monster reborn is limited so you’ll have to get rid of 2
I know you probably won’t, but with the new master rule, you’re gonna need link monsters to summon your synchros.
Goyo and Magician of faith got an errata and they’re different from their first printings, they got ruined essentially.
I suggest a trip to the wiki just to check the link mechanic so you understand it a bit better how it works now
