when you play with 1 deck, if you have a card (eg. dragon), you cannot get another dragon, and your opponent cannot get any dragon. however, it is not like this in infinite deck. here it is possible to have a hand of only dragons.
imagine a deck of playing cards. if you have the ace of spades neither you nor your opponent can get it until it is shuffled back into the deck.
but if you play with infinite decks, there are several aces of spades, and so you and your opponent could both have one, you could have more than one in your hand, etc.
i've also found that in infinite decks, sometimes some cards do not come at all, whereas in single decks, most cards come before a certain card comes twice. |
