I was able to cast Benevolent Geist (the disturb side of Malevolent Hermit) from exile after collecting it with Evelyn, the Collector. Disturb should only work from the graveyard.
I experimented with reproducing it. It seems I can only do this if the Hermit gets exiled from the library, not if it gets exiled from the battlefield.

I can also cast it with disturb from the top of my library with The Reality Chip.

happens because CardFactory builds the KW earlier now, so MayPlay gets to mess with it
I'm not sure there's an easy fix available unless you can think of something :/
