[LV1][LV2]
(During Opponent's Turn) Each time 1 or more yellow spirits you control are destroyed, you may summon a spirit card from your hand that has "Pentan" in its name without paying its cost. In that case, (When Summoned) effects of that spirit are negated.
[LV2]
(During Your Battle Phase) Each time an attacking spirit you control that has "Pentan" or "Empereur" in its name is blocked by a spirit with the same LV, if that attacking spirit is exhausted, refresh it.
