That being said, I don't have that same luxury with the more obscure decks so generally speaking, unless there's a lore specific reason of limiting cards to certain quantities due to their uniqueness (for example only 1 copy of each Crystal Beast existing), 2 or 3 copies are acceptable in order to preserve the feeling of the deck as it appeared in the anime
In the Commander format of Magic: The Gathering every card is legal to play except for banned cards and the ones illegal in all formats
