Mana Counter

Mana Counters are one of two types of counters that can be put on top of face-up cards on the field. Mana Counters can be collected on any card type, typically when the card is summoned due to their Knowledge Stat, and can be spent by the card's controller to pay for mana costs. As with other counters, damage counters are persistent as long as the card is face-up on the field.
