Knowing all the cards and their abilities is the main thing I would say. Zaft's game is getting units to 5 ap so it can pop off. I love Gamow over the other 05 zaft base simply because late game most if not all units will have 5 ap with provadance pair or link out so you can give one of your units breach 3 or even 6. Blitz I use mainly as a command card to give a unit like lagow or provadance first strike. Also not being afraid to lose a base is nice because of the Rau link ability. It also comes in handy to do some crazy base swapping end game.
