g3 - I have an amazing hand with Bazaar, City, Darkblast, Chewer, and 2 dredgers. It was the best post board hand I saw all day. That would win against 95% of the match-ups out there. Unfortunately, he plays Leyline turn 0. I did not expect him to play Leyline at all because he I saw Jailers and and T.C. game two. He later tells me that he only runs 1 Leyline as in his board. I am both pissed that he saw it and I disagree with his logic of only running it as a one of in Bomberman. You should run 4 Leylines or no Leylines; consistency is better than a silver bullet.
To be fair, you're the one who signed up for a tournament playing ichorid with exactly 0 answers to a Leyline of the Void so you knew going in that if someone started a game with a Leyline you were left to 1 power beatdown. Coincidentally playing no answers to leyline also means you can't complain when you lose to one.
Playing 1 Leyline of the Void is actually totally fine, because it means that you can play more flexible ichorid hate while also being diverse. You can build a real sideboard then jam in 1 Leyline and be in a position where you are happy if your opponent sideboards in Emerald Charm or Wispmare or whatever answer they have to leyline because its going to be a blank so often for them while also having that random shot at locking them out completely the times that they don't sideboard to beat your singleton.
To be fair, emerald charm is never really a blank. Untapping Bazaar is pretty good in most occasions, it can cause a turn 2 (or turn 1 with lotus) victory. Wispmare, of course, is a different matter, but generally, you just want something for leyline that you get to side in G3 if you lost to it G2. Leyline, despite it's failing numbers, is the only card you cannot win through if it comes down T0 (jailer is another such card, but you can unmask/therapy, or just stock up before it hits).
