Yami Yugi vs. The Shadow Queen

This is a Duel for my Yu-Gi-Oh! / Paper Mario: The Thousand Year Door Crossover fanfic.

Duel Recap
Life Points: 4000 / 4000

Cards in Decks: 40 / 40

Matt's Turn

 * Discards "Swift Gaia the Fierce Knight" from his hand to Special Summon "The Tricky" in Attack Position (ATK: 2000 / DEF: 1200).
 * Sets a card.

Shadow Queen's Turn

 * Normal Summons "Shadow Grunt" (ATK: 1000 / DEF: 1000) in Attack Position.
 * Activates Spell Card "Dark Siren", preventing Matt from drawing cards for two turns, but Matt activates his set Quick-Play Spell Card "Bounce" to transfer the effect over to the Shadow Queen. She chains it with "De-Spell" destroying said Spell Card.

Matt's Turn

 * Sets a monster in Defense Position.
 * Activates Spell Card "Rebellion", making "Shadow Grunt" attack the Shadow Queen directly (Shadow Queen: 4000 -> 3000).

Shadow Queen

 * Activates Spell Card "Lightning Vortex", discards a card to destroy all face-up monsters on Matt's side of the field.
 * Attacks the facedown monster with "Shadow Grunt", revealing the monster to be "Marshmallon" (ATK: 300 / DEF: 500) who inflicts 1000 points of damage to the Shadow Queen's Life Points (Shadow Queen: 3000 -> 2000) and also Marshmallon cannot be destroyed in battle.
 * Activates Continuous Spell Card "Ghoul Spore", allowing all her monsters to deal piercing damage.

Matt's Turn

 * Sets two cards.
 * Normal Summons "Alpha The Magnet Warrior" (ATK: 1400 / DEF: 1700) in Attack Position.
 * Attacks and destroys "Shadow Grunt" with "Alpha The Magnet Warrior" (Shadow Queen: 2000 -> 1600).

Shadow Queen's Turn

 * Activates Continuous Spell Card, "Miracle Reverse"; This requires the Shadow Queen's Life Points to be below 2000 to activate. Now Life Points of both players will reset to 4000 and they combine their Graveyards and Hands with their decks, shuffle, and draw five new cards.
 * Normal Summons "Gastly Imp" (ATK: 1900 / DEF: 1200).
 * Attacks Matt directly with "Ghastly Imp" (Matt: 4000 -> 2100)
