Yixlid Jailer and the new Flash Kill

[PhilipJFry]

Could somebody please walk me through the effects that a Yixlid Jailer on the board would have on the Flash kill, particularly with each of the major players in the combo? 

How does Yixlid Jailer interact with the Protean Hulk trigger?

How does Yixlid Jailer interact with Body Double trying to copy a Hulk or Reveillark in the graveyard?

How does Yixlid Jailer interact with Reveillark's leaves play trigger?

I should know the answer to these, but I have read conflicting accounts, and could really benfit from someone walking me through the situation.  Thank you very much!

Yixlid Jailer has no effect on Protean Hulk's leaves play trigger.
Yixlid Jailer has no effect on Body Double being able to copy cards in the graveyard.
Yixlid Jailer has no effect on Reveillark's leaves-play trigger.

The one thing Jailer might card about, depending on what you define "the Flash kill" as, is what the power and toughness of creatures in the graveyard is.  A Yixlid Jailor in play will leave any Tarmogoyfs in the graveyard as 0/1.  Yixlid Jailor will remove the power and toughness setting characteristic determining abilities (CDA) from the creatures in the graveyard.
