A Spirit Card Master can choose to use several cards at the same time. But the rules won't let you exploit any loopholes. If you use two cards, you must summon the Card Spirits of those cards. Once a Card Spirit appears, it constantly consumes spiritual power. Normally, Spirit Card Masters can't control two at the same time. However, there are exceptions. Some people are just extraordinarily gifted; such Spirit Card Masters are inevitably among the best of their level.
The referee seemed somewhat surprised. "You're going to use two cards?"
Wen Jiang looked up at her opponent and curled her lips slightly. "Not this time."
No matter what card I use, he's no match. Taking out another would just break his spirit completely.
