Margaret Mai Beaufort is the Yu-Gi-Oh! The Duelists of the Roses incarnation of Mai Valentine and portrayal of Lady Margaret Beaufort. She is a member of the Red Roses of Lancaster.

With the White Roses of York well ahead in their struggle for power with the Red Roses, Margaret secretly requested a high druid, Simon McMooran, to summon a duelist from another age. The player takes on the role of the duelist summoned.

If the player chooses to side with the White Roses, they face Margaret at Canterbury after defeating T. Tristan Grey. After defeating her, the player goes to Dover where they take a boat to France.

The player can obtain "Dust Tornado" by using the find ability on E7 while playing against Margaret.


Margaret's Deck consists mainly of monsters that gain a bonus from the Mountain terrain and equips to support them, including many cards from the "Harpie" series.
