Scrap Archfiend is the only generic one here, though...
Yeah, we should've gotten a couple more generic ones (Gaia Knight, Scrap Archfiend and a LV5 like Gishilnodon or Scarred Warrior would have been nice.) But it's not THAT bad honestly. And Azure-Eyes and Hyunlei are better Synchros than I'd have expected first-up.
Gaia the fierce knight and Lost city are easiest to farm with parabros-elements unite if u want to get cards from SD's only. Abyssal designator, final destiny, owner's seal are the examples of good card
This is my own deck and it has a 90-95% succes rate against standard duelists after exesive testing and you can change the monsters to whatever strong monsters you have but the ECs and Windstorm and Mirror wall is 100% necesary to have a consitant win rate and this deck works fine with auto duels and you can swap out the Riryoku as the AI is quite bad at using it properly
