Stifle, probably a dumb question

[serracollector]

Can you stifle graveyard abilities, such as genesis and squee?  Thanx.

Yes and yes.  Squee and Genesis both have triggered abilities.  However, note that with Genesis, if you stifle the ability, the mana is never paid because it is paid upon resolution of the trigger, like Decree of Justice.

k, thanx, just didn't know for sure if stifle could "target" abilities used from the grave.  I assume this also stops going to grave abilities such as Academy Rector's, and if so, is it still removed or is that part of the resolution also?  sorry for the stupidity, just resolution timing is still new to me on some cards.  Thanx.

You can target any activated or triggered abilities on the stack with Stifle, regardless of where their source is.

If you Stifle Rector, it stays in the graveyard as the choice to remove it from the game is made upon resolution.
