Standstill+Stifle

[Bera]

Posting here because I've heard mixed resolutions regarding standstill's interaction with stifle.

Player A has a standstill, Player B plays a spell causing standstill to trigger, Player B responds to the trigger with stifle. Am I correct in assuming the stifle will cause another trigger to be put on the stack? Or will standstill have sacrificed itself resulting in standstill being unable to trigger a second time.

You are correct in assuming that player B's Stifle will cause the Standstill to trigger again.  The reason is the (very important) "if" clause in Standstill.  Only upon resolution of Standstill's trigger is it sacrificed, at which point the players draw cards.

Then the additional triggers will resolve (edit: if there are any - or they may be countered by Stifle, etc.), but won't do anything because Standstill isn't sacrificed.

So yeah, waste of a Stifle

This is also tricky with Trickbind, but I'm assuming the sacrafice trigger doesn't use the stack

Standstill triggers whenever a spell is played.  On resolution, it is sacrificed, and the players draw cards.

Trickbind is no different than Stifle in this case.  With the Standstill trigger on the stack, player B plays Trickbind, targeting Standstill's trigger.  Standstill then triggers again, and it's the same case as with Stifle.  Standstill will resolve and it will be sacrificed and players will draw cards.  Then Trickbind resolves and counters the first Standstill trigger, but that doesn't matter because Standstill was already sacrificed (thus making the first trigger do nothing).
