Cosmic Monster

Cosmic Monsters are a type of Monster Card, first seen in Yu-Gi-Oh! Cosmos!. The color of their card frame is Light Green on the left side, going in gradients until its light blue on the right. These cards are placed in the Extra Deck.

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

Like other Extra Deck monsters, Cosmic Monsters cannot exist in the hand or Main Deck (even with card effects). If a Cosmic Monster would be moved to the hand or Main Deck, it is returned to the Extra Deck instead.

The main difference with all other monster types is that Cosmic Monsters have 2 Attributes: one primary, to the right of the card name, like all monsters, and one Secondary, to the lesft of the card name. For example FIRE and EARTH, or LIGHT and WIND, etc. Unless otherwise Stated, cards which affect Attribute (like DNA Transplant) only affect the Primary Attribute, not the Secondary

= Cosmic Summoning = Main article: Cosmic Summon

A Cosmic Summon is the act of Summoning a Cosmic Monster from the Extra Deck using monsters from your field that match the Attributes of the Cosmic Monster that you will summon. During the Main Phase 1 or 2, the turn player can Cosmic Summon a Cosmic Monster from the Extra Deck by sending monsters they control to the Graveyard (at least 1 monster of the Cosmic monster's primary attribute and 1 of the secondary attribute), provided the total Level of those monsters matches exactly the Level of that Cosmic Monster.

While most Cosmic Monsters require at least 1 monster of each of its attributes, there are some that may require more, Infinity Cosmos being an example, as it requires 2+ DARK monsters and 2+ LIGHT monsters.

Some Cosmic Monsters require some of its monsters to be of specific Types. Infinity Void requires to have at least 1 Stellar-type monster used as its material, Marvelous VILLAIN Eros requires to have at least 2 Warrior-type monsters as its materials, and Infinity Galaxy requires all of its materials to be Stellar-type.

= Playing style = Cosmic-Based Decks Usually have a large number of monsters, swarming capabilities, Level and Attribute manipulation and Attribute variation.

Strategically Speaking, Cosmic Decks can have similar speed and Power than Synchro-based decks, having similar Summoning requirements.
