Traptrix Sera, Traptrix Rafflesia and Traptrix Holeutea are the strongest cards in this deck.
Lord of the Heavenly Prison and Torrential Tribute are not at all necessary for this deck to function well.
An ideal hand going first is 1-2 Traptrix monster(s), 1-2 "Hole" Trap(s), a Hand Trap, and Parallel eXceed.
Ideal opening for this deck is Traptrix Pudica / Traptrix Myrmeleo / Traptrix Mantis. Link Summon Traptrix Sera. If Parallel eXceed is in hand special summon them and xyz summon Traptrix Rafflesia. Set Traps and extend into Traptrix Pinguicula/ Traptrix Allomerus if possible.
If Nibiru is a possible threat, always xyz into Traptrix Rafflesia as soon as possible.
Alternatively Traptrix Pudica (getting Traptrix Garden) into Traptrix Dionea (or Traptrix Mantis getting Traptrix Arachnocampa)
is also a great way to get both Traptrix Sera and Traptrix Rafflesia onto the field.
Traptrix Holeutea with Traptrix Sera on the board is: backrow protection, Spell/Trap removal or creature removal. During your turn, Traptrix Holeutea is an extender. Do not be afraid to pitch 'Hole' traps to summon her immediately. Especially because you can just special Traptrix Dionaea with Traptrix Sera off of the activation to set that pitched trap to the field.
Traptrix Arachnocampa is only decent if searched with Traptrix Mantis or Traptrix Pinguicula or in a chain to protect your traps.
Traptrix Pinguicula and Traptrix Pudica/any destroy and banish effects are amazing.
Time Thief Redoer is amazing if Traptrix Holetea is used as material.
Temple of The Kings is amazing in this deck. It allows immediate activation of Traptrix Holeutea without having to discard trap (especially if you don't have one), the repeated use of a "hole" with Traptrix Cularia and immediate protection against hand traps if played on turn one with Gravedigger's Trap Hole.
Lord of the Heavenly Prison is great backrow protection and great for grabbing spells or Traptrix Holetea.
Torrential Tribute is included because all extra deck Traptrix monsters are unaffected by trap effects, it doesn't target and sometimes one or two trap holes aren't enough to stop your opponent from running away with the game.
Pot of Prosperity pitch cards generally are: Traptrix Cularia, Traptrix Allomerus, I:P Masquerena, Knightmare Unicorn, Traptrix Sera and Traptrix Atypus / Underworld Goddess of the Closed World
