I've heard players in my area claim that legally slow playing (ie; playing the clock to win strictly on time) is an art. Blows my mind, imo it's a dirty way to play. For example, during the SP era, one of the said players was bragging that he was playing an SP deck without a Mewtwo LvX counter, and he knew his opponent ran Mewtwo Lv.X going into the match. His plan was to take an early lead and then run out the clock. Apparently it worked. He said how he would use SP Radar and take a very long time searching, asking for cards left in deck, etc etc. I think he should have lost that game if that was the manner in which he won. Just to be clear, if he had won on time anyways but didn't abuse the clock, then I do think he would have deserved the win.
I think the clock is and should remain an important part of the game. A good deck can struggle with the clock, a good example being the Chandelure/Accelgor/Vileplume deck this past Nationals. I think that kept it in check. Some games simply would not end if it weren't for the clock in the rare example of a stalemate. The clock should regulate the game, but players should try not to play the clock. Some players may do so unknowingly, I know I have been told to increase my playing speed before. I think Judges should be quick to catch if a player is taking their time thinking or if they are just playing dirty. It's far too easy to legally stall.
