I thought it would be a good idea to make 3 Decks for each major character in the series.
These Decks could be switched around when battled in a game, instead of always the same one (it adds variety, unpredictability and difficulty this way). I kept 1 copy of banned cards only, but still decided to use them (even though some of them might be considerd cheap). Mostly the games have different Decks for each character (Tag Force), but they scale up in difficulty instead of all of them being tough to beat (it's a good practice, but more advanced players will find this more interesting, I believe).
In a possible future, I might consider adding a Side Deck to each of them.

The DM Era Decks follow the Goat Format's Banlist, but they may also have a few extra cards (namely, cards that were released afterwards but still appeared on the first anime).
This is Yugi's "Gadget" Deck. The machine monsters were not in the Goat Format yet, but they're iconic to Yugi's Deck (and are in it; that same logic goes for Gandora, Monster Reborn and Dark Hole).
There is no way to compare Decks with Gadget monsters, but we can create them on our own.
"I think it turned out fine"
And saying that, is an understatement already...
