I notice that everyone always wants to play the latest and greatest characters in this game. I've done fairly well bringing back older decks, as I notice new cards in the newer sets that work with them. I usually play standard format tournaments, so that's mostly what I'm focused on.
For instance, around the time that the Grievous starter came out, people started playing that version of Grievous. But I noticed that many of the new cards like Bacta Therapy, Grievance Striker, and the Punch Dagger work well with the old Grievous from Way of the Force, so I paired him with the Sentinel Messenger and a newer plot and got a great deck out of it.
I also recently decided to bring back Piett with two Mandalorian SuperCommandos ("Papercuts"). Cards like the Bounty Hunter Mask, Riot Shield, Measure for Measure, and Desperate Measures seem to make this just as good, if not better, than the older version.
And don't get me started on Vader. He's been solid since AtG released, yet many people have stopped playing him, for no obvious reason.
Does anyone have any other older characters that you still play, or have brought back for new decks using more recent cards?
