Kaiba is preparing to summon Obelisk The Tormenter, but Yugi activates his facedown Trap Card, Lightforce Sword. It will randomly attack and lock out one card from Kaiba's hand for three turns. He's going to target Obelisk, but he knows he can't control which card the Lightforce Sword hits.

He commands the Lightforce Sword to attack, and it hits a card... which was nothing other than Obelisk. Yugi is satisfied that he'll have three turns to deal with Obelisk, but he knows his next moves will have to count.

Since the summon was negated, Yugi regains control of the Queen's Knight. Kaiba has the XY Dragon Cannon destroy Alpha and he ends his turn.

Yugi draws, sets another card facedown, summons Big Shield Gardna (100/2600) in Defense Mode, and passes his turn to Kaiba. Kaiba draws, then plays the Z Metal Caterpillar (1500/1300) in Attack Mode, and combines it with the XY to create the XYZ Dragon Cannon (2800/2600). He has it destroy Yugi's Big Shield Gardna, but Yugi was waiting for that. He then activates his Line Of The Soul Trap Card, allowing him to pay 1000 Life Points to summon out a Level 4 or less Monster from his deck when another Monster of his is destroyed.

He pays 1000 Life Points (Yugi's Life Points: 3000) and summons the King's Knight (1600/1400), and since it's on the field at the same time as the Queen's Knight, he can automatically summon a Jack's Knight (1900/1400) from his deck. Kaiba then plays a Magic Card called Heavenly Edict. It allows him to pay 1000 Life Points to name a Level 8 or higher Monster, and if Yugi has it in his deck, he gives it to Kaiba. Kaiba pays the cost (Kaiba's Life Points: 2000) and chooses Slifer The Sky Dragon. Yugi pulls Slifer from his deck and gives it to Kaiba, but then activates Exchange, letting each player take one card from their opponent's hand.

The two approach each other and Yugi takes Slifer back, while Kaiba takes a Trap Card called Shortened Life. Kaiba then sets one card facedown and ends his turn.

Yugi draws, then sacrifices his Knights to summon Slifer The Sky Dragon (5000/5000). He knows that Kaiba's going to play Shortened Life sooner or later. When it's activated, Yugi will have to discard cards from his hand equal to the number of turns it was facedown. He attacks the XYZ with Slifer, but Kaiba activates Emergency Teleporter, teleporting the XYZ away from the attack for one turn.

On Kaiba's turn, the Lightforce Sword expires, sending Obelisk back into Kaiba's hand. He then sacrifices the XYZ to summon Obelisk The Tormenter (4000/4000)!

Now that both players have their God Cards on the field, whose will win?
