Katsuya Jonouchi and Mai Kujaku's Duel (manga)

Joey and Mai's Duelist Kingdom Duel was a Duel between Joey Wheeler and Mai Valentine during the Duelist Kingdom tournament.

The Duel used an early set of Duel Monsters rules which differ largely form the Yu-Gi-Oh! Official and Trading Card Games. In the manga, the terrain was 40% mountain, 40% grassland and 20% desert. In the anime, it was 40% mountain, 40% forest and 20% meadow.

Prior events
Joey was looking for his first opponent in the tournament. Yami Yugi advised him to choose a terrain that suited his Deck. (In the English anime, Yami advised him to find an opponent at his level.) Since his Deck contained mostly Warrior and Beast-Warrior-Type monsters, Joey thought the grassland would be fine.

Mai had wanted to Duel Yami, but thought it was a bad strategy to face him straight away. Planning on beating weaker Duelists and gathering more Star Chips first, she challenged Joey to a Duel.

Since Joey had only one Star Chip and Mai was a powerful opponent, Téa Gardner tried talking Joey out of accepting the Duel, as losing would result in his elimination. She asked Yami to talking him out of him, but Yami wished Joey luck. Joey had hoped Yami would say that as he wanted to accept the Duel rather than be remembered as a coward.

Joey and Mai each bet one Star Chip. Before they began, Joey asked Mai why she entered the tournament. Mai replied that she wanted the prize money to spend on glamour. Joey said that was a weak reason and that he was fighting to save a life.

The Duel
Mai used her Aroma Tactics, in which she had scented her cards with various perfumes, allowing her to tell what they were by their smell. She used to tell what her cards were without looking and passed it off as a sixth sense.

In the manga, Mai went first. In the anime, Joey went first.

Joey Summoned "Masaki the Legendary Swordsman" in the grassland (ATK: 1100 → 1430).
 * Joey's turn (anime only)

Mai Summoned "Harpie Lady" in the mountains (ATK: 1300 → 1690)
 * Mai's turn

In the anime, "Harpie Lady" battled with "Masaki". Since land monsters were disadvantaged against flying monsters, "Masaki" lost its Field Power Bonus. (ATK: 1430 → 1100) and was destroyed by battle. (Joey: 2000 → 1410 Life Points)

Joey was distracted by Mai's Aroma Tactics. He Summoned "Tiger Axe" in the grassland (ATK: 1300 → 1690) and attacked "Harpie Lady". Since land monsters were disadvantaged against flying monsters, "Tiger Axe" lost its Field Power Bonus (ATK: 1590 → 1300) and was destroyed in battle. (Joey: 2000 → 1610 Life Points [manga], 1410 → 1020 Life Points [anime])
 * Joey's turn
