AUTO[V]: Limit Break 4 (This ability is active if you have four or more damage): When this unit attacks a vanguard, this unit gets Power +5000 until end of that battle. AUTO[V]: [Choose one of your «Great Nature» rear-guards, and retire it] When this unit's attack hits a vanguard, you may pay the cost. If you do, choose up to one «Great Nature» from your hand, and call it to Rear-guard Circle.
