Notes and Rules Information for Thought Prison:
  • Only the English version of a Magic card receives Oracle updates and errata. View this card in English. (Scryfall note)
  • The second ability triggers only once per spell. If the spell shares both a color and a mana value with the imprinted card, Thought Prison deals 2 damage, not 4. (2004-12-01)
