The basic conceit is this: youre a mighty wizard (player) and you use your book of spells (deck of cards) to battle your opponent until their health is depleted (their points are at zero.)

Special Summon up to 2 monsters with different names from your hand and/or Deck, that mention "Umi" or are WATER Normal Monsters, in Defense Position, then if your opponent controls a monster, you can Special Summon any number of Level 6 or lower WATER Normal Monsters from your hand and/or Deck
The same is true for Pokemon Pocket where players are haunted by getting 11 Haunters from their promo packs
The surface of the card will show advanced stages of wear, including scuffing, scratching, pitting, chipping and staining
