Its the same as the rules for turning a Morph or Disguise creature face-up: any effects which trigger from unlocking the door WILL use the stack and allow opponents to respond as normal, so this ends up sounding scarier than it is in practice

Its limited by being a sorcery, sure meaning you need to be the one killing creatures off but it makes up for it by being lethal in the same way as Monumental Corruption
