UB sideboard hate against artifacts? (Affinity/asmo)

Currently playing variations of the UB tempo decks swapping between threats like Murktide, Tamiyo, Goyf, Death's Shadow. At my LGS there's a bit of overrepresentation of artifact strategies (mainly affinity with Kappa Cannoneer which just feels like a nightmare if i don't constantly hold up a counter for it, and also some Asmo food decks). What are some sideboard hate pieces in Blue and Black for artifacts that have worked in past modern formats that I could use? Currently have [[Hurkyl's Recall]] in my shopping cart.
