Im a new player, but iv played a fair few games with seamus. the best peice of advice I can give as a newbie is get a range of models. crookeds sound like the best to me. Place the shafted markers and the blasts for board control. Do blasts ignore armour?
I think it may be what a lot of people are thinking but, Dr Mc would be a better match up for you but I dont want to say go buy a new crew
