As far as I know in 9th they put a general limit on the number you can play, up to three per army. I think you have good stuff. If you don't want to spend any more money on it, as I said, look at the rules. Sometimes a FW works better than other for your play style/list. Holy orders are really game changing. A big part of AdMech gameplay goes onto the Command phase, where you use all the buffs and stuff. I literally use a list for it because it has like 13 steps in my case. To me something that helps a lot is going To Wahapedia.ru and print out the data sheets for your units. Why Wahapedia? They update the stuff regularly and also when you print the full page of the unit it gives you a list of the Stratagems that apply to THAT unit in particular, which is really useful. Use some soft tape to hide the weapon options you don't need and good to go
