I don't have very strong thoughts regarding Comic of the Month, but while I'm in this thread, I do have two suggestions for you to consider.
I'd like to see in-depth interviews with players who have recently won or finished well in PvP, asking them about their strategy, description of a couple key decks, opponents, critical matches, etc. You could do this for a tournament, or Trials, but I think it would be ideal for PvP Events and War.
Another idea I have is monthly puzzles to determine the maximum probability of winning the game within a certain number of turns, given what cards you have and the cards remaining in your deck. This idea is less promising however, because it is more difficult and would probably be less appreciated.
