#117 Altar of the Moone - Guardians Rising (sm2)

Altar of the Moone is a Trainer card from the Sun & Moon series, specifically part of the Guardians Rising set released on May 5, 2017. It is classified as an Uncommon rarity card and is illustrated by 5ban Graphics. The card functions as a Stadium-type card, meaning it remains in play after being played unless another Stadium card is also in use. Its primary rule reduces the Retreat Cost of all Pokémon with Psychic or Darkness Energy attached by Colorless, affecting both players' cards. Additionally, the card must be discarded if another Stadium card enters play, and it cannot be played again if a card with the same name is already active. The card’s unique interaction modifies gameplay mechanics by altering Retreat Costs dynamically. Its design emphasizes strategic adjustments to resource management during battles. This card’s rules create conditional effects that influence both offensive and defensive strategies in gameplay.
