Send 1 "Phantom-" Spell/Trap Card from your Deck to the Graveyard. When an opponent's monster declares a direct attack while you control no cards and this card is in your Graveyard: You can Special Summon this card in Defense Position as an Effect Monster (Warrior-Type/DARK/Level 4/ATK 300/DEF 600). (This card is NOT treated as a Trap Card.) If Summoned this way, banish this card when it leaves the field. While this card is treated as a monster, it gains 300 DEF for each "Phantom-" Spell/Trap Card in your Graveyard.
