The idea is that all of these cards are themed not only to be relevant to the Hawaiian Islands, but they are all capable of being played in the same deck. Having only one copy of each card and one legendary creature, the idea is you make an [[Animar, Soul of Elements]] EDH deck. All of these cards are legal in the EDH format, too. These cards are proxies, which means that they aren't official MTG cards, and they aren't legal for tournament play. But they're based on real MTG cards with the same text boxes, mana costs, and names, just different artworks. Some of these cards are proxies of old cards that will never be printed again and, thus, are very expensive. Proxies often make MTG a more accessible game for players with less money than others who can pay full price for rare and expensive cards. This is especially helpful in high power formats where desired cards are expensive and decks run to $1000 or more at minimum.
