You can fight everyone, and will have to fight a bit, but the enemy leaders both have Protect, and the main goal is to rescue Durant. Or, as it were, place both Yggdra and Milanor by him. Also, try to let Durant fight as little as possible, mostly becuse he cannot gain EXP while he's neutral, so it's a waste. Durant will join your party when you rescue him. Use an average of eight or less cards per part for the MVP Bonus.
