Removed from that context, I actually really like Goreclaw, Terror of Qal Sisma
The Black common instant three cost digs your domain, and then draw two, the rest head to your graveyard, you lose two life
I expect that well never get an instant for 1B that just destroys any creature, but the more options that we get for restricted removal spells the closer we get to having approximately that card exist for any given Cube
Unless you fancy leaning into the (fairly random) vehicle subtheme that Revival Trance is sporting with cards like Setzer, Wandering Gambler, Id recommend cutting that fat and adding some more solid reanimation-focused picks like Alesha, Who Laughs at Fate or Caesar, Legions Emperor
Havi can be used to return legendary cards of lesser mana value when a legendary creature dies, allowing for some level of recursion to retrieve important legendary creatures
