Mats would depend on what mag and equips you will use on it, if its a mostly power mag/units then you won't need as many power mats and could add other mats. Using freeze/confuse traps help a lot if you can get into that. And equips, do you want end game ones? The equips that in my opinion are the best to have would be guld milla, charge/demon yas 9000, Arrest Needle, zalure shot or needle, master raven for blowing up traps fast and a frozen shooter
Edit: Anything hell is good to have as well
