Uh, it is not open to more tactics.
the First and Second generations (WotC produced up to Skyridge, the 16th set, and only the first three actually appeared in the games) revolved around 4 decktypes: Haymaker, Stall, DO THE WAVE and Exeggutor.
If anything, the new cardsmakes the game more open to different tactics and deck styles.
the WotC era is liked because they were "old school" and everybody recognizes them, but it's when Pokemon USA that the cards start to get actually decent and the game skyrockets in popularity.
You're entitled to your opinion that the original was the best, but it shows that you haven't played the newer sets yet (you'll know that there are very little changes to the game, and if anything, it's easier and more fun to play), and it's ignorance like that which annoys me.
