The shape indicates which set, or edition, that particular card was printed in, and the color indicates the rarity , as follows: Cards printed before the Exodus set in 1998 did not use colored symbols to show rarity, and many of these cards have no set symbol at all
As long as this acrd is attached to a Pokemon, it provides every type of Energy but provides only 1 Energy at a time.If the Pokemon this card is attached to is Knocked Out by damage from an attack from your opponent's Pokemon, that player takes 1 fewer Prize card
It also introduced the Ring of Destruction Trap card, which doesn't compare to ring-based cards in other TCGs like Magic: The Gathering , but still sees some use today thanks to the damage it's capable of doing to players' Life Points
