Dragunity Pilum (HAC1-EN160) [Hidden Arsenal: Chapter 1]

When this card is Normal Summoned, you can Special Summon 1 Winged Beast-Type "Dragunity" monster from your hand, then equip it with this card. While this card is equipped to a monster, that monster can attack your opponent directly. When you do, Battle Damage inflicted to your opponent (by the equipped monster) is halved.
