In tennis, two pairs of great players often face off against each other as teams in doubles tournaments.
Here's a wuxia doubles sword tournament:
Yeung Gor and Little Dragon Girl from Jin Yong's RETURN OF THE CONDOR HEROES mastered a synergistic combination of Cheun Jen Sword Technique and Ancient Tomb Sword Technique to create a nearly flawless style of swordfighting that enabled the couple to defeat even Greats-level fighters like the Golden Wheel Monk. Many ROCH fighters considered Yeung Gor and Little Dragon Girl's double swords technique invincible.
Sai Mun Chui Sheut and Yip Goo Sing from Gu Long's LUK SIU FUNG were considered Sword Gods. Individually, each of them was considered the very pinnacle of what a swordsman could be. Combined, their combat ability is beyond imagination. When Sai Mun Chui Sheut threatened to team up with Yip Goo Sing to force their way out of the Imperial Palace in Beijing, the Royal Guards thought that even the combined force of the palace's 3000 elite guardsmen would not be able to stop them.
So . . . Sai Mun Chui Sheut and Yip Goo Sing vs. Yeung Gor and Little Dragon Girl.
NOTE: for the purpose of this discussion, this is Yeung Gor before losing his arm and obtaining Dook Goo Kau Bai's Heavy Iron Sword, and before Little Dragon Girl learned Left/Right Hand Technique and could perform the double sword technique by herself. Also, Little Dragon Girl will not be able to call up her bees, use needles, etc. This is a straight sword fight. Both teams will have to rely on their swordfighting skills, nothing else.
The winning team will take on Dook Goo Kau Bai himself.
