I know that in TCGOne you can post your own decks and make them public and write a short sentence about how it works, but here people can view the decklists and give constructive feedback. Feedback is always important and there isn’t really a way to give feedback when playing the game.
That is an excellent idea and there are already plans to bring this feature to the forum. Basically, we will have a new deck editor which will make a forum post when complete, then people will be able to comment on every deck, using the existing forum facilities.
