Sentence of Doom

You can target any number of your Fiend monsters that are banished or in your GY, up to the number of "Destiny Board" and/or "Spirit Message" cards you control; add them to your hand. You can send this card from your Spell & Trap Zone to the GY; place 1 "Spirit Message" card from your hand, Deck, or GY in your Spell & Trap Zone. (This is treated as being placed by the effect of "Destiny Board".) You can only use 1 "Sentence of Doom" effect per turn, and only once that turn.
