When a Spell/Trap Card, or monster effect, is activated while you control an "Orcust" Link Monster: Negate the activation, and if you do, banish that card. You can banish this card from your GY; add 1 DARK Machine monster from your Deck or banishment to your hand. You cannot Special Summon the turn you activate this effect, except DARK Machine monsters. You can only use 1 "Orcust Crescendo" effect per turn, and only once that turn.
