Campaign Characters good for Arena?

[The__Wanderer__]

So a few times in Arena I’ve gone against opponents using characters from campaign on their team that applied stalkers mark and others that applied demoralizing roar and I got cooked. So my question is, is it possible to create a functioning team from these characters? Liashi Arablest are one of the characters I captured from a mission that have stalkers mark And Liashi Siege Golem is another character that has demoralizing roar. if you search them up on the honrbound wiki it shows them as their listed abilities.
