You can only use this card name’s effect once per turn.
(1) If you control no monsters: You can banish 1 other “Blackwing” monster from your hand; place 1 “Black Whirlwind” directly from your Deck to your Spell & Trap Zone face-up, then, you can either send this card from your hand to the GY, or immediately after this effect resolves, Normal Summon this card from your hand without Tributing a monster. The “Black Whirlwind” placed by this effect is sent to the GY during the End Phase, and you take 1000 LP. You cannot Special Summon monsters from your Extra Deck for the rest of this turn, except DARK monsters.
