Yu-Gi-Oh! Guardian Duel

''Yu-Gi-Oh! Guardian Duel'' is a Yu-Gi-Oh! card game first released in January 2022. It brings elements from old games like ''Yu-Gi-Oh! Forbidden Memories and Yu-Gi-Oh! The Duelists of Roses''.

Gameplay

 * There are 3 Monster Zones and 3 Spell & Trap Zones. Also there is 1 Field Zone, and an Extra Deck limited to 5 cards.
 * The Deck consists of 40 cards.
 * Players start the Duel with five cards in their hand. During their Draw Phase, the turn player draws 1 card, and the same applies to the person who starts the duel first.
 * Players can Normal Summon/Set as many monsters as they want in a single turn, as long as they have the appropriate Deck Cost. Level 5 and higher monsters must still be Tribute Summoned normally.

Guardian Stars
Each monster has 2 Guardian Stars which you have to choose from, different from each other. They are: Sun, Mercury, Venus, Moon, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto. They play a role in deck building and while supporting monsters.

Deck Cost
During each of your turns, you gain 100 Deck Cost (DC for short). With that, you need to pay DC to Summon monsters or activate Spell/Trap Cards. DC is calculated as such:
 * For monsters, the DC equals the sum of ATK and DEF of the monster divided by 100 (rounded up if the result is not a whole number).
 * For Spell/Trap Cards, the DC is determined of how strong the power level of said card is. More powerful Spell/Trap Cards have higher Deck Cost.

Gender
The gender of the card is a reference to the anime effect of "Shadow of Eyes" and the manga effect of "Number 22: Zombiestein", and only play part in effects.
