Hey there! I was on a doubles tourney last week with my Imperial Fists. Played with my friend with Blood Angels and the thing went really well. This situation got me into seriously building my Fists army starting with the Land Raiders :P
Got myself some stuff and hopefully you will see the results somewhere in this space soon.
I've got another tourney on Saturday, this time based on the Clash of Heroes scenario from the brand new Battle missions book. Can't wait for this one, you'll have full scale report this time ;)
