Sneak Attack + Stifle

[S1N1STER]

I wanted to make sure I understood this right in case I every get to pull it off in a game. I put am Emrakul or Progenitus into play with sneak attack, sneak attack creates a delayed triggered ability "sacrifice the creature at the beginning of the next end step." So at the end of my turn can I cast stifle targeting the triggered ability and keep my creature in play?

Yes.

Yes.

From Oracle: "You may put a creature card from your hand onto the battlefield. That creature gains haste. Sacrifice the creature at the beginning of the next end step."

Can someone confirm?

I hate this uber-quote, but it's definitely a delayed trigger, and not a "part of the same ability". You CAN stifle the sacrifice trigger.

Okay,

Guess I'm wrong. Thanks!

404.4. An effect may create a delayed triggered ability that can do something at a later time. A delayed triggered ability will contain “when,” “whenever,” or “at,” although that word won’t usually begin the ability. 404.4a Delayed triggered abilities come from spells or other abilities that create them on resolution. That means a delayed triggered ability won’t trigger until it has actually been created, even if its trigger event occurred just beforehand. Other events that happen earlier may make the trigger event impossible. Example
Part of an effect reads “When this creature leaves play,” but the creature in question leaves play before the spell or ability creating the effect resolves. In this case, the delayed ability never triggers.
