Notes and Rules Information for 探源装置 // 晶岩石室:
- Only the English version of a Magic card receives Oracle updates and errata. View this card in English. (Scryfall note)
- The value of X for Geode Grotto's last ability is determined only as it resolves. Once that happens, the value of X won't change later in the turn even if the number of artifacts you control changes. (2023-11-10)
