Card Rules: Rulings powered by The Netrep API. 'Shield Crush' can select and destroy monsters in face-up or face-down Defense Position. 'Shield Crush' will only destroy the selected monster if the selected monster is still in Defense Position when 'Shield Crush' is resolved. For example , if you select a Defense Position monster to destroy with 'Shield Crush' and the monster is changed into Attack Position by another card effect ('Zero Gravity' etc.) the effect of 'Shield Crush' disappears. 'Shield Crush' targets the Defense Position monster that is selected when you activate 'Shield Crush'. If the selected monster is changed into Attack Position after being selected it is not possible to select a different monster. [Re: Prime Material Dragon] 'Prime Material Dragon's' second effect works like 'My Body as a Shield'. 'Prime Material Dragon' can negate cards such as 'Smashing Ground' 'Nobleman of Crossout' 'Shield Crush' 'Thousand Knives' 'Trap Hole' 'Mirror Force' 'Ring of Destruction' 'Torrential Tribute' 'Bottomless Trap Hole' 'Swarm of Scarabs' 'Dark Armed Dragon' 'Raigeki Break' 'XYZ Dragon Cannon' 'Mega-Ton Magical Cannon' 'Exiled Force' (negates the effect but will not destroy 'Exiled Force' as it is already in the Graveyard) 'Soul Taker' (negates 'Soul Taker' so you do not gain Life Points) 'Jowgen the Spiritualist' (when its effect is activated) 'Dragon's Gunfire' (if the effect that destroys a monster is selected) or 'The Last Warrior From Another Planet' (negates the effect and destroys 'The Last Warrior From Another Planet').
