Sorry, both can be used, but not at the same time
take a wound, dont do both rolls
shrieker cannons are ok, but seeing what other choices you have for your WL I d swap it
You could get more troops for those bikes, but whatever your playing style
More Death Jesters(Take shuriken cannon off one)
Not sure how you can get these in there, seeing as ive just said things to add, not subtract.
