Card Rulings:Abyss Soldier

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.
