Learn to Play Demo The " Learn to Play Demo " is a 15 - minute 30 - second video made in 2009 at http : / / www . yugioh - card . com / en / gameplay / demo . html . It replaced the " Interactive Demo " . Yusei Fudo instructs Leo and Luna basic gameplay mechanics , while also referring to the viewer in second - person . It is available in multiple languages due to yugioh - cards ' multilingual function . At the end of the video , Yusei and Leo play a short instructional duel , both using TCG rules and . It is only a rudimentary tutorial , as it fails to explain several mechanics , such as only briefly mentioning Fusion Monster s and Ritual Monster s , and aspects of Chain s . Other parts are improperly explained , such as set ting monster s . Synopsis . In the video , Yusei explains the six Phase s : Draw Phase , Standby Phase , Main Phase 1 , Battle Phase , Main Phase 2 , and End Phase . The different actions , according to Yusei , are listed below : Draw Phase : You draw one card from your deck . Standby Phase : Nothing specific happens unless a card says so . If it does , follow the instructions on the card . Main Phase 1 : 1 . Summon a monster from your hand 2 . Change the Battle Position of a monster on the field 3 . Set or activate Spell Card s 4 . Set or activate Trap Card s Battle Phase : You can attack your opponent using monsters you control . Main Phase 2 : It ' s just like Main Phase 1 . Since your opponent ' s turn is coming up , you should strengthen your defense . But remember , if you already summoned a monster during Main Phase 1 , you can ' t summon again during Main Phase 2 . 1 . Summon a monster from your hand 2 . Change the Battle Position of a monster on the field 3 . Set or activate Spell Cards 4 . Set or activate Trap Cards End Phase : You declare the end of your turn . After listing them and a general list of each action one can take in each Phase , he then goes in - depth in each of the different actions one can take in each phase . Main Phase 1 . Yusei first explains Main Phase 1 , and describes Normal Monster s and Effect Monster s . He explains they can be summoned in Face - up Attack Position or Face - down Defense Position . ( This is erroneous ; monsters placed in Face - down Defense Position are considered set , not summoned . ) Yusei says monsters are meant to attack the opponent or to protect Life Points . He then goes on to explain the rules of Tribute Summon ing , Special Summon ing , and Synchro Summon ing . Leo is eager for Yusei to explain the Battle Phase , but Yusei continues to explain usage of Spell and Trap Cards : Spell Cards : Usually played during your turn . You can use them right from your hand . 1 . Say the card ' s name . Put the card from your hand onto the field . 2 . Follow the instructions , then place it in the Graveyard . Trap Cards : You have to Set them face - down on the field before you can use them . Trap Cards can be used even during your opponent ' s turn . 1 . You can only use Trap Cards after you Set them face - down on the field . 2 . Say the card ' s name and flip it face - up . 3 . Follow the instructions , then place it in the Graveyard . Battle Phase . Yusei mostly explains the Damage calculation . The two types of battles he explains is a monster attacking a monster in Attack or Defense Position . Attack Position vs . Attack Position : If the attacking monster is attacking a monster with lower ATK , the attacking monster destroys the attack target by battle and the difference in ATK is subtracted from the other player ' s Life Points . If the monsters have equal ATK , both monsters are destroyed and there is no change in Life Points . The video fails to explain what would happen if the attack target has higher ATK than the attacking monster . Attack Position vs . Defense Position If the attacking monster is attacking a monster with lower DEF , the attacking monster destroys the attack target by battle , with no change in Life Points . If the attack target has DEF equal to the attacking monster ' s ATK , neither monster is destroyed with no Life Point change . Leo inquires what if the attack target has higher DEF than the attacking monster ' s ATK . Yusei explains neither monster is destroyed and the attacking player loses Life Points equal to the difference of the attacking monster ' s ATK and the attack target ' s DEF . Luna then asks what if the opponent has no monsters , and Yusei explains Direct Attack ing . Featured Duels : Yusei Fudo vs . Leo . Leo explains that prior to starting a duel , both duelists are to greet each other . Yusei then says each player shuffles his own deck , then shuffles his opponent ' s deck . He also says the Main Deck is placed in the Deck Zone and Synchro Monsters are placed in the Extra Deck Zone . Afterwards , he says a random method is needed to determine who goes first , such as flipping a coin or playing rock - paper - scissors . Leo picks rock and Yusei picks scissors , allowing Leo to decide to go first . Turn 1 : Leo Leo Sets a monster and two Spell or Trap Cards . Turn 2 : Yusei Yusei ' s opening hand is " Scrap - Iron Scarecrow " , " Quillbolt Hedgehog " , " Junk Synchron " , " Speed Warrior " , and " Unstable Evolution " . He draws " Sonic Chick " and Normal Summon s " Speed Warrior " . The effect of " Speed Warrior " allows its ATK to double to 1800 during this turn ' s Battle Phase . Yusei attacks with " Speed Warrior " , but Leo activates " Widespread Ruin " to destroy " Speed Warrior " before damage calculation . Yusei Sets " Scrap - Iron Scarecrow " . Turn 3 : Leo Leo Flip Summon s " Des Koala " . Its Flip Effect inflicts 400 damage for each card in Yusei ' s hand . ( Yusei 8000 → 6400 ) Leo Tribute s " Des Koala " to Tribute Summon " Saber Beetle " and attacks directly . Yusei negates the attack with " Scrap - Iron Scarecrow " and Sets it back down . Turn 4 : Leo Yusei draws and activates " Tribute to the Doomed " by discarding " Quillbolt Hedgehog " . Leo activates his face - down " Magic Drain " to negate " Tribute to the Doomed " . Yusei chooses not to discard a Spell Card to negate the effect of " Magic Drain " . Yusei summons " Junk Synchron " and uses its effect to Special Summon " Speed Warrior " from the " Graveyard " . He then Special Summons " Quillbolt Hedgehog " with its own effect and equip s it with " Unstable Evolution " to increase its ATK to 2400 . Yusei uses " Junk Synchron " and " Speed Warrior " to Synchro Summon " Junk Warrior " . The effect of " Junk Warrior " activates ; it gains ATK equal to the ATK of all Level 2 or lower monsters Yusei controls ( " Junk Warrior " 2300 → 4700 ) . " Junk Warrior " attacks and destroys " Saber Beetle " ( Leo 8000 → 5700 ) . " Unstable Evolution " changes the ATK of " Quillbolt Hedgehog " to 1000 , as Yusei ' s Life Points are higher than Leo ' s . " Quillbolt Hedgehog " attacks directly .
