I am the noob. I am cutting my teeth and dakkadakka has helped enormously. I have lurked and read everything I could find about da boyz before posting.
There are two leagues that are getting ready to start up. i have a post in the lists thread (no one has replied to

) about the larger league, but I just entered a 500 point league as well. i am excited about it because it will allow me to understand the other armies and grow with the league. (500 points jan/feb, 750 mar/apr, 1000 may/jun, 1500 july/aug. )
I know there will be a few blackreach ork lists and marine lists. I have quite a few models and can field about anything that could be put in the list.
I was thinking big mek with
kff bosspole and burna, 30 sluggas with nob with powerklaw and bosspole, and 20 shootas with 2 big shootas and a nob with powerklaw and bosspole.
Is that realistic? How can it handle the marine dred? Deffkoptas?
Thoughts on tactics and strategies?
