Ive just started playing Ethan's Typhlosion and have seen that every deck on limitless plays drakloak, is there a reason why this is so heavily preferred over dudunsparce? I understand that drakloak isn't completely disrupted by watchtower like dudunsparce, but then why wouldn't other decks prioritise drakloak for the same reason?

Thanks in advance!
