I still play Zekrom because it's a non-EX attacker, which I feel I need. It's also very helpful in many cases in that I can hit for 120 damage reliably with less risk and/or investment than if I used Mewtwo EX. I'm trying to decide what might be a better card to use over it, but Zekrom seems solid enough to use in the deck. I had to remove two Zekrom from the list I had before, and then Mewtwo became easy to come by, thankfully. I also play four Tynamo because I don't want to worry about losing most of my Tynamo early in the game if any are prized.
