Yes, you already have.
How much of a life saver is this card?
Activate only when you take Battle Damage while you control no monsters. Gain Life Points equal to the Battle Damage you took, and Special Summon 1 "Malus Token" (Fiend-Type/DARK/Level 1/ATK ?/DEF ?). Its ATK and DEF are each equal to the amount of Life Points you gained by this effect.
It is out in the next pack.
