This card is treated as a Normal Monster while face-up on the field. While equipped with a "Noble Arms" Equip Spell, this card becomes an Effect Monster with these effects. ● This card becomes DARK and its Level is increased by 1. ● During your Main Phase: You can reveal 3 "Noble Arms" cards from your Deck, have your opponent randomly add 1 of them to your hand, and send the rest to the GY. You can only use this effect of "Noble Knight Borz" once per turn.
