Core leaves
When you have no monsters on the field, you can Special Summon this card from the Graveyard. When this card is used as XYZ Summon Material, it protects that XYZ monster from being destroyed by Battle. Normal summoning this card can add its twin from the Deck to the hand, which is great for thinning out your deck. A Starter card that combines with Skills, so put 3x copies of it in.
NOTE: the protection effect only lasts once per turn, meaning if you summon xyz with a second copy of the monster in the same turn, xyz will not receive the protection effect.
When normal summoning this card, we can banish it to special summon Buzzsaw Shark. (usually) or Right-Hand Shark from the deck. Also a one card combo starter and an extender. You can play x2-3 copies if you don't have enough 3 cards of other monsters, otherwise 1 copy is more than enough.
Skill and Cards in Skill
You select 1 monster and it gains 1000 ATK for the rest of the battle. You can select any monster except Full Armored Utopic Ray Lancer , Cat Shark and non-Water XYZ monsters will be covered later.
NOTE: You usually use this card for the second effect of the Skill: discard it to summon Full Armored Utopic Ray Lancer , avoiding revealing other cards to the opponent.
You equip an xyz monster from the GY to a monster on the field, it will gain 3 effects: The monster's Atk, Attribute will be equal to the Atk and Attribute of the XYZ card. . If that monster attacks, you can send the xyz card to the GY to punch it again. You will use this card to end the game early or in difficult games, use it on normal monsters when you cannot summon XYZ
NOTE: When attacking for a second turn, the ATK of the attacking card will return to the original. You cannot attack 3 times if you use this card on Full Armored Utopic Ray Lancer because both cards have the "second attack in a row" line (2 punches) which conflicts with your attempt to perform "3 punches". Similar to AQUA JET, this card is often used to give the second effect of a skill, Discard it for utopic.
You can Target 1 monster on the field and negate its effect, this effect can only be used when you use the Skill's 2nd effect and give this card 1 material. Great for forcing your opponent to use an early diruption like Unchained Soul of Rage before you start your combo . Always use this card as material for Utopic Summon.
Note: This monster is considered a SPECIAL SUMMON BUT NOT FROM THE EXTRA DECK meaning it can negate Borreload Riot Dragon and Borreload Furious Dragon , it can be targeted by Unchained Soul of Rage but cannot be targeted by Nekroz of Brionac .
Tech card
Extra Deck
You can see the main character's aura by looking at it. A Water Number 39: Utopia monster that you can summon by using an xyz monster on the field and discarding 1 spell/trap. Reduces the ATK of all opponent's monsters by 500. Negate does not target all effects of monsters on the opponent's field, during the Battle Phase, and when it kills a monster, it can attack again. Must play.
NOTE: If you use an xyz monster with Hand Shark as material to summon utopic, utopic will not be protected from Destroy. ATK Reduction is a continuous effect which means it affects both Borreload Riot Dragon and Borreload Furious Dragon . The Negate ability that occurs at the start of the Battle Phase (your turn or your opponent's turn) activates before entering the Battle Phase or you will miss activating it.
Being where this card belongs, this is a win condition against unchained, negating half of borrel link's playstyle including their rokket float, half of infernoble fleur's playstyle, Sky Striker Airspace - Area Zero summon and Sky Striker Ace - Raye reborn, and the hand shark combo in mirror matches. This card's ATK will always be 2200 (unless there are no more xyz materials left). Must have.
If you summon it with Left-Hand Shark , it no longer costs to activate its effect because it can target itself and another card, the wolf won't be destroyed due to its protection while the other card will go away. Great for fishing backrows or clearing the field for a finisher.
NOTE: Utopic Ray Lancer and Black Ray Lancer are both Beast-Warriors, you can destroy them if necessary.
When playing cairngorgon, I often play it with this card. When declaring an attack, it reduces your opponent's monster by 1000 ATK. When it is destroyed, you can revive any other monster. Useful for endgame punches or enough damage to punch Hamon, Lord of Striking Thunder and Raviel, Lord of Phantasms .
You summon this monster with a Rank 3 Water monster with no xyz materials. It has a one-time destruction protection effect by detaching all xyz materials from the monster. If it destroys a card, you can also destroy a Spell/Trap on your opponent's side of the field.
