I have more news, and it may explain both Chaos Sorcerer and Demise.
Due to Konami reversing a long-standing ruling, the priority rule for Monster with Ignition Effects is void as of March 18th.
In other words, if Bottomless Trap Hole or Compusory Evacuation Device is used when a Monster like Demise or Chaos Sorcerer is summoned, it does NOT get priority and does NOT get to use its effect. It is removed from the field before the effect can occur. Starting March 18th.
I can provide the link if you need it.
