Well, wether the horn deck, nor the Gil-Galad combo should be changed. The hunters block is balanced, as it is the standard format.
Be aware: do NOT change cards! That would divide the playership and ruin the game. As I have said before, the horn deck and even the troll swarm are not overpowered!
Card changing can not be handled by players, because it is a subjectif view of sight.
There is just one thing to change, indeed, I think : "
Frenzy of arrows". And for this, I would suggst to get 150 subscriptions of players all over the world (do not forget Asia!!!) to accept the new card.
And, if Decipher gets ready with Fight Klub: Collect all rule questions with examples, so we can give them to decipher.
Election would be nice.
