XX-Saber Fulhelmknight

Efeito

When your opponent declares an attack, you can select the attacking monster, and negate the attack. You can only activate this effect once (while this card remains face-up on the field). If this card destroys a Defense Position monster your opponent controls by battle, you can select 1 Level 4 or lower "X-Saber" monster in your Graveyard, and Special Summon it.
