In the event that a card's cost basis varies (box break, trade, or you forgot), the cost basis entered in for your asset is up to your discretion. There isn’t a ‘right’ way to do this, however, you could distribute the cost evenly based on the number of cards pulled or distribute based on the value of the cards.
Cost basis does not impact ALT Value. It is only used to calculate returns and for personal reference.
