No replacement for x23, she's unique because she let's you play 6 cost cards like knull on 5, and another 6 cost card plus a deadpool on 6. You could consider running Magik for a similar purpose. You could replace Nico with forge to power up deadpool, or yondu/squirrel girl to power up Knull and Death (since both of these replacements lower Death's cost by getting killed by killmonger)
