純粹法力

Raw Mana is a 0-cost purple mana card granting +1 mana — but as "unrefined" mana it carries a drawback. The mana replenishment is attractive, but the risk requires management. Compare against Mana Book (stable, no downside) before committing.

Typical drawback patterns: temporary damage reduction, card lock, or mana conversion loss.

1. Wild (mitigate drawback while maintaining combo)
2. Yin-Yang (mana refill + draw combined)
3. Free to Play (if it reduces drawback exposure)

Arcanas: Mana Syphon (max mana scaling synergy), Sharp Mind. Crawlers: Arca (all mana-related), Porta. Relics: Mana-boosting relics, Polentir.

Raw Mana is a risk-reward mana card. Mana Book is the safer default. Use Raw Mana when combo chains break due to mana shortage and the risk is acceptable. Understanding the specific drawback is critical before building around it. Arca and Porta can partially offset certain drawback types through their mana manipulation abilities.
