Desecraton Demon, Skirsdag High Priest, Triggered Abilities

[Everforward]

{Desecration demon}+ {Skirsdag High Priest}
Can I activate skirsdag in response to them sacrificing creatures but before the desecration demon becomes tapped

[Keyeto]

You may not. Once Desecration Demon's ability begins to resolve, it resolves completely. The sacrifice and tap are both done during the execution of a single ability, so no player has priority at that time. You can't respond to the sacrifice by tapping {Desecration Demon} since it will be tapped the next time you have priority to activate the ability of {Skirsdag High Priest}.

This is similar to how you can't {Cloudshift} {Vexing Devil} to save it from being sacrificed.
