so I have your answer but its going to rain on a parade here. you cant take a marshcrawler in current kruleboyz list. it doesn't currently have it and even if you try and make a kruleboyz list in the new app its not listed. so the correct answer here is that you actually have 300 points to play with because the marshcrawler is an illegal choice. you could include any number of the listed choices you want in that 300. personally I like the idea of taking a killaboss on foot, a shaman, and a unit of hobgrotz for maximum use but you could take a kb/mirebrute or mirebrute/shaman as choices as well. sorry to be the one to point out that marshcrawler currently doesn't have kruleboyz keyword.
