It's great to hear your enthusiasm! It's always exciting when the new cards come out!
From reading posts of many gets over the past few years, it sounds like they each have discovered some particular strategies that work well fairly consistently for them. jpav's posts on the secret formula are a great example. With a couple of dozen great threads like that , it's almost like there's a great strategy book for strat-o-matic scattered through these threads. Palmtana and others have done a really nice job gathering up the links to these great threads. Look for palmtana's thread on the strategy board.
But I think each player has to find their own particular strategies that work well for them. So keep plugging away, and keep building on your own successes.
Good luck!!! Have a great time with the new cards!!!
