Destroy 2 monsters on your opponent’s field for no cost.
You can only activate this card if you do not have any Trap cards in the graveyard.
It is best to run this card in a deck that doesn’t use any other Trap cards.
You cannot activate this card when you have another copy of it in the graveyard. What you can to is turn on self chain so that you can activate 2 of these at the same time, destroying all your opponent’s monster.
Here are some cards to help you remove Trap cards from the graveyard so that you can use Treacherous Trap Hole. Use the effect of Diskblade Rider to remove from play Trap cards in your graveyard and gain an attack boost. Pot of Benevolence can return Trap cards back to your deck allowing you to reuse them.
You only can activate it in response to card activation that TARGET it, cards like Geargiattacker and spellbook of fate doesn't target card so yon can only activate Treacherous Trap Hole when these cards are activated not after selecting the cards to destroy.
I always have a enemy controller to outplay this card. I literally won a match once because they activated it.
They had a stardust out as well as a face down monster and I was basically empty field summoning one monster at a time.
I managed to get my last crystal beast into gy. I suspected they had TTH set but I knew I had an econ set as well. I summoned Rainbow Dragon and they TTH'd like I expected targeting their facedown and rainbow. I chained econ to TTH by tributing Rainbow Dragon,ECON resolves first and takes control of Stardust, then TTH goes off destroying their facedown. I normal summon Amber elephant and swing with lethal.
