"Traptrix Atrax", "Traptrix Myrmeleo", "Traptrix Nepenthes" and the characters from the "Trap Hole" archetype. Artwork is from "Traptrix Trap Hole Nightmare".
The pets of the "Traptrix" girls are all creatures known for using holes to trap their prey. Nepenthes' pitcher plant lures insects into a chamber with unclimbable walls filled with digestive fluids. Myrmeleo's antlion simply waits at the bottom of a pit dug in sand until something falls in. This pit is cone-shaped and the floor is made of loose sand that is also unclimbable. Atrax's funnel-web spider sits at the bottom of its tubular web and grabs anything that disturbs one of its tripwires with its strong and highly venomous fangs.
The archetype is centered around using "Trap Hole" and "Hole" cards to activate various effects. Each Traptrix is immune to Trap Hole cards themselves, while also adding support by tutoring Trap Holes or each other. With these traits, a Traptrix deck will usually have good opening moves, since they can react quickly against virtually any monster your opponent may Summon.
Note that "Traptrix Atrax" also extends her anti-negation protection to other Normal Traps, so the Deck can also run "Mirror Force", "Dimensional Prison", and even make a temporary one-sided anti-Trap lock using "Trap Stun".
Further useful yet indirect support exists for the archetype through the use of their types. Insect and Plant support cards may be sufficient to satisfy the deck's hunger for competitiveness. An example to this is "Gigaplant", "Beetron" and "Lonefire Blossom". Also the fact that they are all EARTH monsters are useful since "Grandsoil the Elemental Lord", "Redox, Dragon Ruler of Boulders" or "Gigantes" can fit in to support them further.
Due to the small number of members within the archetype, in addition to their reliance on numerous Trap Cards, Traptrix is most suitable as an Anti-Meta strategy, by controlling the field using Traps and slowly gaining resource via either "Traptrix Myrmeleo" or "Traptrix Nepenthes", while at the same time grinding out your opponent's resources. "Traptrix Myrmeleo" can also be splashed in other decks, along with "Traptrix Trap Hole Nightmare" and other Trap Hole cards for covering the deck's weaknesses and giving a little defense boost.
"Royal Decree", "Jinzo", "Goblin Pothole Squad", "Forced Ceasefire", "Dark Simorgh" and similar "anti-trap" cards can severely hinder the Deck unless you control a face-up "Traptrix Atrax", who prevents the activation AND effects of your Trap Cards from being negated. Also, any Decks that running "Forbidden Lance" (or Decks that runs any "unaffected by trap" monster such as "Troposphere") can evade their Traps easily and still destroy their monsters, making them quite a nuisance.
Since most of the Trap Hole cards can only be activated upon monster's Summon, Traptrix-based deck may have difficulties against decks that designed to have a large set-up quickly (this is more apparent if you go second), such as Karakuri and Dragunity. To remedy this, mass-removal cards such as "Mirror Force" are highly recommended. You may also want to fit a few Counter Traps (or even "Breakthrough Skill") to handle a monster with anti-destruction ability, such as "Stardust Dragon" (in case you cannot have "Traptrix Atrax" quickly).
