Aggressive Reaction
I find that the best defensive strategies attack. When you let the opponent dictate the terms of an interaction (“this game is about my Jitte“) you have to play by his rules; you may mistakenly enter a mindset where you believe that the game revolves around some key permanent he uses to threaten you, even when it only looks that way, or only is that way because you let it. You grasp for even sub-optimal methods of answering that permanent in the vain hope that its removal is, like Love in the Beatles song, all you need. The problem is that when the opponent controls the initiative, you can’t hope to win with one-for-ones.
