My decks with hare apperant, persistent partitioners, and rat colony are invalid because they have to many copies of one card where the cards say they can have any number of cards in a deck.

I took out a card checked if it was valid and put it back in and took out a different card and did this for every card in the deck and the only thing that “fixed” it was taking out all but one of my hare apparents even tho they say I can have any number of them in the deck.
