Forum:Obelisk the tormantor question

I have call of the haunted that was set my previous turn, and I have obelisk the tormentor face-up on the field with another monster card on my side of the field, my opponent's has monsters on the field, during mainphase 1, I activated obelisk the tormantor by tributing itself and another monster to destroy all monsters on my opponents side of the field, After that can I activated call of the haunted to special summoned obelisk the tormentor, would I now be able to attack directly with obelisk the tormentor?96.44.92.186 (talk) 18:00, June 14, 2013 (UTC)
