You should try not to rely on dt to much gets predictable and you can do so much more with asc. Like why fair into dt when yo can fair asc fair asc dtilt/dj fair asc (dependent on height/di) and dt in smash attack can catch some off guard and get a sneaky kill if used sparingly. but best option from dt is uptilt and a mix up is if they expect that approach and go into shield/spotdodge dt to get behind them and grab them or just uptilt asc them and they will most likely get caught off guard because the uptilt is delayed because you didnt dt cancel it. If they managed to still shield it you have a ton of options you can do to pressure them or to land a grab. I keep going on but nahh.
