Psychosis crawler/jaces archivist

[Quackmaster5]

If I activate  {Jace's Archivist} activated ability, would my  {Psychosis Crawler} die?

I know it's a "discard, then draw" but since it's one ability, Does it happen simultaneously?

It wouldn't. Yes your crawler would be a 0/0 during the resolution of the ability however state-based is only checked before an after the ability not during so it wont die.

As a general rule just remember you can do anything in the middle of doing something else.
