Tất cả thành viên của series này đều có Quick Effects anti-meta được thiết kế để gây rối cho đối thủ bằng cách vứt bỏ chính chúng.
Trong OCG, mỗi lá bài đều có tên mang nghĩa kép. Ví dụ như, tên OCG của Ghost Ogre & Snow Rabbit" (幽鬼うさぎ Yuki Usagi) theo nghĩa đen là "Drifting Ghost Rabbit" nhưng phát âm gần giống như "Snow Rabbit" (雪兎 Yuki Usagi). Tên TCG thì lại bao gồm luôn cả hai nghĩa.
As stated before, all of them have disruptive effects and are used as Hand traps:
- "Ghost Ash & Spring Flowers" negates any effect that either moves a card from the Main Deck to the hand, Special Summons a monster from the Main Deck or sends a card from the Main Deck to the Graveyard. This can be deadly if used against cards with high costs and/or restrictions, such as "Pot of Desires", "A Hero Lives", "Left Arm Offering" or "Darklord Ixchel". It can also avoid the floating effects of monsters like the "Yang Zing", "Gusto", etc., and prevent a player from capitalizing on their opponent's string of Special Summons with "Maxx "C"".
- "Ghost Ogre & Snow Rabbit" sends itself from the hand or field to the Graveyard in order to destroy a face-up card that has activated its effect. Despite the fact it does not negate its "target", this may put the opponent in a difficult position, as they will have lost one of their combo pieces. Also, it is particularly effective against Continuous Spell/Trap Cards, because they have to remain on the field in order to resolve their effects, as well as some monsters, such as "Naturia Beast" and "Zombie Master".
- "Ghost Reaper & Winter Cherries" discards itself in order to banish all copies of an opposing Extra Deck monster, after a copy of that monster has been revealed from "Ghost Reaper"'s owner's Extra Deck. This can be used to get rid of powerful monsters that are traditionally the lynchpin of some strategies, such as "Cyber Dragon Infinity", "Toadally Awesome", "True King V.F.D., The Beast", "Crystal Wing Synchro Dragon" or "ABC-Dragon Buster".
