Power Man & Iron Fist #64 pits the heroic duo against evil brothers Muerte (Death) and Suerte (Luck). Suerte's talents enable him to win a game of poker against other crime bosses within the issue. Although Suerte uses ordinary playing cards in the story, the cover creatively pictures the heroes and villains on a hand of cards. Trying to find irrefutable meaning in the cards, however, is challenging.
As the stars of the series, Power Man and Iron Fist both appear on the cover as Aces. Power Man's suit is Clubs while Iron Fist is Diamonds. (Within the issue, incidentally, Bob Diamond of the Sons of the Tiger describes himself as an "ace" martial artist and a sparring partner to Iron Fist.)
As for the villains, Suerte appears as the Eight of Diamondsthe same suit as Iron Fist. Suerte's pet cat is also an Eight but instead holds the suit of Clubsthe same suit as Power Man. Meanwhile, Muerte appears as the Jack of Spadesa different rank and suit from everyone else on the cover.
