Sneak Attack

[Falcon182]

ok rules dudes:

I have a  {Sneak Attack} on the battlefield. During what phase of my opponent or my turn can I activate it after the end of turn sacrifice trigger would have gone off on my opponents turn and before my own untap?

[griffin131]

During their End step you can activate it, but not before it.

[LinkCelestrial]

Guys. {Sneak Attack} + {Sundail of the Infinite}. Any creature for {2}{R} with haste.

[InfinitiveDivinity]

During their End step you can activate it, but not before it.

Wouldn't there be a priority pass upon activation and after?

Guys. {Sneak Attack} + {Sundail of the Infinite}. Any creature for {2}{R} with haste.

Not relevant to the question.

[griffin131]

Yes, there would be. End step begins, opp passes priority, you activate Sneak, pass, opp passes, resolves, opp passes, you pass, cleanup, your untap.
