Crown Monster

Crown Monsters Are a type of Monster Card, first seen in Yu-Gi-Oh! Cosmos!. The color of their card frame is a dim green. These cards are placed in the Extra Deck.

To be properly Special Summoned, Crown Monsters must first be Crown Summoned. If they leave the Extra Deck without being Cosmic Summoned, they cannot be Special Summoned while they are banished or in the Graveyard.

Unlike other Extra Deck monsters, Crown Monsters can exist in the hand or Main Deck. A Crown monster that is returned to the Hand or Deck by a card effect, goes there without issue.

A Crown Summon is the act of summonning a Crown Monster from the Extra Deck using Monsters and Spells, and Traps from your field. The total level of the used monsters plus the total amount of Spells and traps must be equal to the level of the monster to summon.

The Spells and Traps used for the summoning are sent to the GY, while the Monsters used as materials stay on the field and are placed under the Crown Monster, like Xyz Overlay units. Unlike Xyz monsters however, Crown monsters cannot use their materials for effects. Instead, when the Crown monster is Destroyed by Battle and sent to the GY, the materials return to the Field and the Crown monster is sent to the GY. This is known as "Dethroning" and only triggers if the Crown Monster was destroyed by battle. If it leaves the field by any other way (Destroyed by card effecfts, shuffled into the Deck, returned to the hand, banished, etc.)

If a crown monster is used as a material for a Crown Summon, its materials are kept, and the same Dethroning mechanic applies for the newly summoned Crown monster.

If a Monster used as a material for a Crown Summon was equipped to a card of any kind (Spell, Trap or a Monster), then they are not sent to the GY, instead, the newly Summoned monster becomes equipped with all the same cards as its materials.
