OCG Rulings

  • While an effect like that of "Banisher of the Radiance" or "Macro Cosmos" is active, it is impossible to discard a card to the Graveyard. The activation costs of the effects of "Jowgen the Spiritualist", "Abyss Soldier" and "Return of the Doomed" require you to discard a card to the Graveyard, which is impossible, so you cannot activate their effects. However, the activation costs of effects like "Magic Jammer" only require you to discard a card, so you can activate their effects since the card does not need to be discarded to the Graveyard.[6]

  • If you have an active Field Spell Card and want to activate a new one, then you first send your old Field Spell Card to the Graveyard and then activate the new one. If your opponent activates "Magic Jammer" to negate the activation of the new one, then the old one has already been sent to the Graveyard, so it does not return to the Field Card Zone.[8]
