Lots of toying around with combinations at the moment. The playstyle of Daemons is really different, and watching streams on the internet has been good homework, learning how other people play. Atm I'm looking at taking a good mix of flying monstrous creatures and larger ground units. I'm also trying to take units that would work well in the current meta. However, trying to cram so many things into the list might leave the individual elements a little too thin. Maybe a dozen games later I'll start getting the hang of this army.
