If this card targets an opponent's face-up Attack Position monster for an attack, and that monster is not destroyed by the battle, this card can attack the same monster again in a row. This effect can only used twice per turn.
local s, id, o = GetID()
function s.initial_effect(c)

	e1:SetCode(EVENT_DAMAGE_STEP_END)
