Welcome to Librarium Online!
I though that you had a 5000 point tyranid army hive fleet matis. And I also thought that you played 127 games and won nearly all of them.
It's really not that simple to beat chaos...
And for God's sake, use punctuation!
#1) Mantis - is english your first language? Please say no.
#2) If you have 5,000 points of Tyranids, why did you make all these posts?
#3) Why do you not understand simple rules from the codex? Are you trolling, or missing info?
