Forum:Atra and Trecherous trap hole

2 questions with this one, firstly since Atra the Mesmerizing Maneater prevents the negation of the activation of trap cards, can I still activate Treacherous Trap Hole if there are traps in the graveyard?

secondly, since trecherous doesn't have a activation requirement like bottomless, can I activate it from my hand at anytime using atra's effect ZGWolf (talk • contribs) 15:00, June 18, 2013 (UTC)
