Situationally very limited. Corp recursion isn't very good currently, so if this allows you to land a Chastushka or a Time Bomb early, that's respectable value for the tempo loss to net damage. Bankhar matches up very well against some common ice like Tollbooth and Sandstone and early-game gearchecks. I would suggest taking more meaning from life than your virtual bird, though.
Although Raindrops Cut Stone quotes Bankhar, I don't think the two work well. Most of the things I'd want to do with Bankhar are high-impact run events. Runs can only use one run event and RSC is probably not enough value for the level of danger that Bankhar invites. If you're running on unknown ice with incomplete breakers, which I think is the most common Bankhar use, you are liable to burst into flames if you hit an Envelopment or Anansi or Endless EULA and can't break it. Bankhar gets safer as the game progresses and you have a better idea what the first ice will be (and have more options for breaking it if you need to).
The card is a connection, and usually, if the card title is a person's name, the person in the artwork depicts that person.— DDarkray
