Bitter ordeal's gravestorm does not work. Steps are:
- put some cards in graveyard (mill, cast, etc)
- Cast Bitter ordeal
- Actual: bitter ordeal resolves exiling one card 4 Expected: bitter ordeal gravestorm is put on stack and bitter ordeal is copied for each card put into a graveyard this turn
It's still bugged as of sept 2021
