Although they are related to the "Hole" archetype through the "Traptrix", they are a separate group of cards. Since all support for the "Hole" archetype also supports the "Trap Hole" archetype, in the TCG, the "Trap Hole" archetype is treated as a subset of the "Hole" archetype.
"Darkfall" (formerly known as "Dark Trap Hole") is not a member of this archetype since its Japanese name does not contain 「落とし穴」 (its Japanese name contains 「落とし大穴」, with the kanji 「大」 interrupting 「落とし穴」). "Chaos Trap Hole" and "Gemini Trap Hole" are "Hole" cards but not "Trap Hole" cards, since their Japanese names contain 「ホール」 Hole but not 「落とし穴」 Pitfall.
Members[]
A knight, an orange goblin, and/or green goblin appear in the artworks of several "Trap Hole" cards.
