I disagree about the planning. Don't need to explain why. And why do you N haters keep bringing up skill? Why don't you have enough "skill" to respond to an N? At least early on you can respond to one. Mistakes made by you after being N'd will cost you and they're usually your mistake not because your opponent played an N. Look at last year's World Championship Final. If Igor didn't play N, he may have won because Andrew got a new hand as well.Disgaree.
ACE-SPECs made the game more luck-based. Any powerful card which can only be a one-of will have this effect, since it requires more luck to find and not to be prized.
N makes planning in the early stages of the game pretty much unlikely. There is virtually no point planning for several turns based on your hand because it is changing all the time. Being able to plan adds more skill, more decision-making. And "Ace Trainer" means we still have a card that helps us come from behind.
Like I said in my last post, don't try to pose as being smart. We all know you, you, you and you include cards years ago people would have said were "skilless" to play but simply were created to respond to the evolution of a constantly changing game.
N is necessary especially for setup decks like Megas or even Stage 2s! Don't you want them to be viable? I find it odd that people keep whining about something they helps them get they want. Or at least make a fuss about. "Stage 2s arent viable anymore. They're too slow and have no support!" Believe it or not losing N is losing another tool for Stage 2s which many of you claim to hate.
