Due to their Japanese names, a number of monsters (mostly WATER monsters), such as "Abyss Soldier" and "Hot Red Dragon Archfiend Abyss" also fall into this archetype. However, because TCG and OCG support for this archetype only works on Spell and Trap Cards that are not on the field, this is not an issue.
"Abyss-" monsters like "Abyss Soldier" and "Abyss Warrior" activate their effects by discarding a WATER monster, while others like "Mermail Abyssgunde" and "Mermail Abysshilde" have their effects activated when sent to the Graveyard. This helps the player to have card advantage over the opponent by adding others monsters to the hand while manipulating the opponent's cards. It is also possible to combine with some of the "Atlantean" cards.
