Good relic for Crossbones?

Hi all!
I just took Crossbones to r3 with the act 8 exploration and was wondering if there is a good relic pair for him?

Comments

Black panther

not sure maybe, Valkryie relic or Winter Soldier

Black widow to pair with his AAR

BW relic no question. Makes him a different beast.

Bw or WS

I use BW since I have a 6* but WS works fine too if you have one.
