Featured Duel :
Kite Tenjo vs. Mr. Heartland

Turn 1: Mr. Heartland
Mr. Heartland Normal Summons "Infection Fly" (100/0). He activates "Hell Multiplication", which allows him to target a Level 2 or lower monster he controls and Special Summon two copies of the same monster from his hand; he targets "Infection Fly" to Special Summon two more "Infection Flies" from his hand. Heartland activates the effect of one copy of "Infection Fly", which lets him double the Level of all the monsters on his field; all three of his current monsters become Level 2. He continues to activate the effects of the other two copies of "Infection Fly", doubling the Level of the three monsters from Level 2 to Level 4 and then to Level 8. Heartland overlays his three Level 8 monsters to Xyz Summon "Number 1: Infection Baal Zebul" (3000/2500) in Attack Position.

As it was Xyz Summoned, Heartland can send a monster from his opponent's Extra Deck to the "Number 2: Shadow Mosquito Ninja" from Kite's Extra Deck to the Graveyard. Mr. Heartland Sets a card.

Turn 2: Kite
Kite activates "Quantum Dragon Ritual", and Tributes "Photon Chargeman" from his hand to Ritual Summon "Paladin of Photon Dragon" (1900/1200) in Attack Position.

He activates its effect, Tributing it to Special Summon "Galaxy-Eyes Photon Dragon" (3000/2500) from his Deck. "Galaxy-Eyes" attacks "Infection Baal" and during the Battle Step, Kite activates the effect of "Galaxy-Eyes", banishing it and the attacked monster until the end of the Battle Phase. At the end of Battle Phase, "Galaxy-Eyes" and "Infection Baal" return to the field and "Galaxy-Eyes" gains 500 ATK for each Overlay Unit "Infection Baal" had before it was banished. (3000 → 4500) Kite Sets a card.

Turn 3: Mr. Heartland
Heartland activates the effect of "Infection Baal", allowing him to attach a "Number" monster from his opponent's Graveyard to it as an Overlay Unit; he attaches "Shadow Mosquito Ninja" from Kite's Graveyard. He activates the other effect of "Infection Baal", detaching an Overlay Unit to destroy a card on the field, and if that card was a monster, his opponent takes damage equal to the destroyed monster's ATK. Heartland destroys "Galaxy-Eyes", but Kite activates "Prevent Draw", halving the effect damage he would take and drawing a card. (Kite 4000 → 1750)
