Quantum Monsters

Quantum Monsters are a type of monster card. The color of their card frame is a transition between blue smoke to bright turquoise, with a slight crystal/prism texture in the background with a purple card border. These cards are placed in the Spell Book.

To be properly summoned, Quantum Monsters must first be summoned by Quantum Summon (unless otherwise specified). If they leave the Spell Book without being summoned correctly, they cannot be summoned while they are in the Abyss or the Catacomb.

Like other monsters in the Spell Book, Quantum Monsters cannot exist in the hand or in the Altar (even with card effects). If a Quantum Monster is placed in the hand or in the Altar, it is returned to the Spell Book instead.

When properly summoned, the turn player must pay 2 resources.

Quantum Arrows
Main article: Quantum Arrows

Quantum Monsters also have Quantum Arrows, indicated by blue arrows for monsters in monster areas or pink arrows for those in non-art regeneration areas. These indicators indicate the areas and monsters that Quantum Monsters point to.

Spell Book monsters (Absorption and Spell Book Prism monsters) cannot be sent from the Spell Book to the Quantum Zone. If a Quantum Monster points to a monster, the monsters are considered "linked" to each other.

Quantum Summoning
Main article: Quantum Summon

A Quantum Summon is the act of summoning a Quantum Monster from the Spell Book. During their main phase, the turn player can summon a Quantum Monster from their Spell Book by sending monsters listed on the card they control to the Quantum Zone as Quantum Materials.

Playstyle
Quantum Monsters generally grant benefits to monsters they point out or gain more powerful effects based on the number of monsters they point to. As such, altars centered around Quantum Monsters require methods of rapidly summoning monsters in order to summon Quantum Monsters as well as in areas targeted by monsters. When trying to summon multiple Quantum Monsters, it's important to decide in which order to summon them, as their Quantum Arrows will dictate where others can be summoned and which monsters will be linked to them.
