I am curious on what all can be blocked by hexproof
With obvious things like fireball aside, it's very good at protecting a players graveyard for specific combo decks against specific hate. It doesn't stop all, but answers cards like tormod's crypt and bojuka bog that target a player. I played a green/white hermit druid deck that piloted sigarda, heron's grace along with cards like scout's warning and savage summoning to flash out druid, or to flash out sigarda to protect my graveyard. This worked well for me, but wasn't a fix-all since things like scavenger grounds exist. But this effect was absolutely clutch in many games.
While it can be helpful this is not an effect that should be put in to every deck.
If you're playing a sort or combo deck that needs ways to protect the graveyard then it makes sense. If you're tuning your deck to answer specific cards your meta is playing, then your probably better to just play better generic answers instead of meta-tuning hate against specific opponents.

This effect also stops random extract and fun effects like praetor's grasp/bribery/mindclaw shaman/gonti, lord of luxury/villainous wealth/etc.
