Turn 10 : Yami Yugi Yami Yugi draws . He passes his turn . Turn 11 : Strings Strings draws . Strings then activates the effect of " Jam Breeding Machine " to Special Summon a third " Slime Token " ( 500 / 500 ) in Attack Position . Strings then Tribute s all three " Slime Token s " to Tribute Summon " Slifer the Sky Dragon " ( X000 / X000 ) in Attack Position . Since Strings summoned a monster ( s ) besides a Slime Token , " Jam Breeding Machine " is destroyed . Due to the effect of " Slifer " , its ATK and DEF are equal to the number of cards in Strings ' hand times 1000 . There are currently two ( " Slifer " : X000 → 2000 / X000 → 2000 ) . By anime mechanics , since " Slifer the Sky Dragon " is also treated as a Dragon - Type monster , " Buster Blader " gains 500 ATK via his effect ( " Buster Blader " : 2600 → 3100 / 2300 ) . Strings then activate s " Pot of Greed " ( " Slifer " : 2000 → 1000 / 2000 → 1000 ) to draw two cards ( " Slifer " : 1000 → 3000 / 1000 → 3000 ) . Strings ' hand contains " Infinite Cards " , " Card of Safe Return " , and " Humanoid Slime " . Turn 12 : Yami Yugi Yami Yugi draws " Lightforce Sword " . Yami Yugi ' s hand contains " Berfomet " , " Big Shield Gardna " , " Magical Hats " , " Dark Magician Girl " , " Spellbinding Circle " , " Lightforce Sword " , and " Kuriboh " . Yami Yugi then Set s two cards and Normal Summon s " Kuriboh " ( 300 / 200 ) in Defense Position . ( Note : " Slifer ' s " effect should have activated here , destroying " Kuriboh " as it has less than 2000 DEF , but by anime mechanics its effect counts as a " special attack " , causing " Nightmare ' s Steelcage " to prevent it ) . On Yami Yugi ' s End Phase , " Nightmare ' s Steelcage " is destroy ed as it has been two turns since it was activated . Turn 13 : Strings Strings draws ( " Slifer " : 3000 → 4000 / 3000 → 4000 ) . " Slifer " attack s " Buster Blader " , but Yami Yugi activate s his face - down " Lightforce Sword " to remove from play one card in Strings ' hand for three turns ( " Slifer " 4000 → 3000 / 4000 → 3000 ) . " Buster Blader " prepares to counterattack " Slifer " , but by anime mechanics , Strings uses the effect of " Jam Defender " to redirect the ' attack ' of " Buster Blader " to " Revival Jam " , destroying it and saving " Slifer " . " Revival Jam " then revives itself ( 1500 / 500 ) in Defense Position through its own effect . Strings activate s " Card of Safe Return " , allowing him to draw three cards whenever a monster is Special Summon ed from the Graveyard . The effect of " Card of Safe Return " activates and Strings draws three cards ( " Slifer " : 2000 → 5000 / 2000 → 5000 ) . By anime mechanics , " Slifer ' s " original attack continues , destroy ing " Buster Blader " ( Yami Yugi 4000 → 2100 ) . Turn 14 : Yami Yugi Yami Yugi draws " Magic Cylinder " . He then Tribute s " Kuriboh " in order to Tribute Summon " Dark Magician Girl " ( 2000 / 1700 ) in Defense Position . The second mouth effect of " Slifer " then activates , which would reduce the DEF of " Dark Magician Girl " by 2000 and then destroy it as its DEF would drop to 0 , but Yami Yugi activate s his face - down " Magical Hats " to hide his " Dark Magician Girl " in one of four hats and shuffle the hats . " Slifer ' s " ' special attack ' destroy s a " Hat " , but it ' s empty . Yami Yugi Set s two cards . Turn 15 : Strings Strings draws ( " Slifer " : 5000 → 6000 / 5000 → 6000 ) . Strings then activate s " Infinite Cards " ( " Slifer " : 6000 → 5000 / 6000 → 5000 ) to remove the hand size limit and allow himself to hold as many cards in his hand as he wants . " Slifer " attack s the " Hat " with " Dark Magician Girl " inside it , but Yami Yugi activates his face - down " Magic Cylinder " and his face - down " Spellbinding Circle " in response . The activated cards resolve in reverse order : By anime mechanics , " Spellbinding Circle " decreases the ATK of " Slifer " by 700 ( " Slifer " : 5000 → 4300 / 5000 ) after its attack has already been launched , while the anime effect of " Magic Cylinder " redirects the original attack of " Slifer " back to it , but Strings activates the effect of " Jam Defender " to change the attack target to " Revival Jam " , destroying it instead . " Revival Jam " then revives itself ( 1500 / 500 ) in Defense Position via its own effect . Strings then draw s three cards via the effect of " Card of Safe Return " ( " Slifer " : 4300 → 7300 / 5000 → 8000 ) . Since card effect s only affect an Egyptian God Card for one turn , " Spellbinding Circle " is destroy ed during the End Phase ( " Slifer " : 7300 → 8000 / 8000 ) . Turn 16 : Yami Yugi Yami Yugi draw s . He passes his turn . Turn 17 : Strings Strings draws ( " Slifer " : 8000 → 9000 / 8000 → 9000 ) . " Slifer " attack s and destroy s " Dark Magician Girl " .
