Traptrix Atrax allows you to activate Network Trap Hole from your hand or protect Network Trap Hole when it is activated on the field. Traptrix Dionaea sets Network Trap Hole from your graveyard letting you reuse it or at least scare your opponent into not Special summoning from their Deck and Graveyard until your next End Phase.
I got 2 of this. So when The Vagabond appeared with Silent Magician deck, I destroyed his SM Lv4 and summoned Lv8 from the deck while I have this card face down, so what I was like "here she goes, be prepared!!" what happened next? NOTHING HAPPENED! The F! What was just happened what happened to this face down card?!
You defeated SM and she SS SM lv8 from deck. Well surely the "defeat" thing happened during damage step and during damage step, only counter trap and trap that modify Atk/Def value can be activated. This is neither one of those.
