1 Insect Tuner + 1+ non-Tuner monsters Once per battle, during damage calculation, if this card attacks an opponent's monster with equal or higher ATK (Quick Effect): You can halve the ATK of that opponent's monster, during that damage calculation only. When this card inflicts battle damage to your opponent: You can inflict 200 damage to your opponent for each "Battlewasp" monster you control. You can only use this effect of "Battlewasp - Halberd the Charge" once per turn.
