Traptrix Pure

Your advantage is when you are being the 1st turn. your priority is set as many as hole trap

as possible. and summon sera then you may end your turn.

 

If you're lucky enough  and you drew The Phantom Knights of Shade Brigandine you can

activate it immediately then it will trigger the effect of sera then special summon any traptrix monster

from you deck I prefer traptrix mymeleo to trigger its effect after special summoned and it will also

trigger the effect of Traptrix Sera to set one "Hole" Normal Trap from your Deck Then Special Summon
Traptrix Rafflesia to protect your Traptrix Sera in any kind of destroy effects.

 

if you Go Second Turn just play defensive and Summon Atrax and Set any cards that protect Atrax Such as
Compulsory evacuation Device or Storming Mirror Force then all your hole trap keep that all in you Hand

and you may End your Turn.

PS.Because of Atrax effect. Your opponent cannot negate your normal trap, not just "hole" trap but any Normal trap.

Ps. You can finish early the game by summoning Pentestag and Utopia Double by attack the defense position monster that had been
Set by the effect of Floodgate Trap Hole.
