The "My Updates" section should notify you of any new answers or comments posted on your questions, or any question that you have selected as a favourite. Under normal circumstances, this is how you could check for any new updates on your posts. In fact, you can try it now; go to the updates page and you should see a notification that I've posted this answer on your question.
The reason your post has not received any comments or answers is that it has been hidden, ie. not visible to the public. The post was hidden (or, more specifically, rejected in moderation) as it appeared to be an in-game team, and also lacked information on EVs. As the Battle Subway section is for competitve teams only, the post was not approved.
From the rules page:
>Competitive teams only: In other words, teams for competitive battling with other people or the advanced post-game sections like Battle Subway, Battle Tower or Pokemon World Tournament. No teams for regular gameplay: there are too many variables for these questions to be useful, and in-game teams do not need much work, just a variety of Pokemon types and moves.
>Include all relevant details: This means all 4 moves for each Pokemon and each Pokemon's ability, nature and EVs (Effort Values). If you don't know about EVs then take a few moments to read our detailed EV guide here. If you are still not sure, put in something basic (e.g. max attack, max speed for a physical sweeper).
