A Crit-based team
While risky, a crit-based team using Mad God Zebra as a leader and a Duel-GX II or Bolt Magus Rashil (Duel-GX II is more effective) for the crit buff can be very effective in quickly depleting Grah's HP pool. Keep in mind that using Fujin Potions or Fujin Tonics is almost mandatory for this team to work.

Leader: Mad God Zebra

Mandatory Units: Duel-GX II OR Bolt Magus Rashil - Fujin Potion/Fujin Tonic should be used on this unit for the Crit buff

Units to Consider:
 * Cyborg Lilith II
 * Pros: High damage single target BB, effective against Grah because of Light element, quick refill rate
 * Cons: Takes higher damage from Grah's regular attacks
 * Evil Blades Logan
 * Pros: High damage single target BB, can heal himself after casting so he has increased survivability
 * Cons: Smaller HP pool than Lilith
 * Any unit with a high ATK stat
