Unsolvable Cube

When used, after allies attack for the first time in the next battle, the attacked enemy target will heal for an amount equal to the HP it lost in this attack. For every 1% of HP the enemy target heals in this way, characters receive a Shield that can block DMG that is equal to 1% of the character's Max HP, up to 100% of their Max HP, lasting for 2 turns.

In the Mystic Cube Dueling Tournament famous throughout the Cosmos, the Cubemaster fills the peoples' magic cubes with a seventh color, sending thousands of foes hurtling off the stage. This unsolvable and devious scheme was finally shattered in the Tenth Amber Era by Dr. Cube. He defeated the Cubemaster on the physical level and then painted the six sides with the same color.

"Isn't physical dueling the focus of the Mystic Cube Dueling Tournament?"
