Shuri or Knull?

Hi everyone, I have the following cards:

I'm missing both shuri and Knull (also I don't have She-hulk (helpful in shuri deck)).

(Also no titania but I can swap her with Ebony Maw)

I have Shuri pinned in the token shop, I was wondering if I should buy her or wait for Knull to show up in the token shop.

Thank you for helping
