For all the only NR players that suffer from the current imabalanced NR cards there might be a tactic that is more out of the box thinking but may work. As long as there is no competitive NR deck possible due to the overpowered NG, Monsters, SK decks, you can do the following:
Built the best NR deck possible for you and start a ranked game. If you draw perfect cards, give it a try and play normally. As soon as only one card is not drwan perfectly just.....WAIT....from the beginning with 12 cards let for each draw the timer go down to 1 second and place your card in the last second. Go for a coffee, play on your cell phone, go to the toilet whil waiting...and let the opponent have the longest possible game. So the price for winning with overpowered decks rises. As you, with your current NR deck, have only a very small chance to win, you don´t have to care if you make 5 games a day or 20. Your win/lose ration will be bad anyway. So with that WAIT-TACTIC you have the chance, that the connection breaks during the game and you get a win or the opponent does not have time to wait anymore. And also, if more and more NR deck players follow that tactic, soon everybody who gets NR deck as opponent knows what awaits him and maybe quits imediately. This tactic is surely the better way to get a positive win/lose ratio for NR at the moment then "playing" the game.
