Artilleur Hyper Psychique LC5D-FR235

1 Tuner + 1 or more non-Tuner Psychic-Type monsters. If this card attacks a Defense Position monster, inflict Piercing damage to your opponent. At the end of the Damage Step, if this card attacked a Defense Position monster and the DEF of that monster is lower than this card's ATK (use the original ATK and DEF if the other monster is no longer on the field), you gain LP equal to the difference.
