I can't help to notice that Team Fire's Deck Builder submission's description is a lot more than 100 words (over 200). I first did a good explanation of how my deck is meant to be used, but after majofa pointed out that it is 100 words max, I had to shorten it quite a bit. And then seeing another submission with a lot more words feels a bit frustrating. I also saw that most other deck submissions was around 96-99 words, so I'm probably not the only one that had to shorten my submission due to the rules.
Now, the rule change was in the middle of last round's thread, with no change in the opening post, so I suggest that for future rounds you'll have the limitation in the opening post, and then if you exceed the limit, either removed description or that the Brawl Masters just remove the end of it or something.
