The 0/9 streaks is doable if you plan it so that you incorporate a milestone reward (some give arena energy). You have to be lucky on the opponents you get when it happens. I believe I haven't made it yet. It seems the game is fixed and gives me 3 epics opponents right when I can do it.

The 0/20 reward is only possible with gems (or if you are really really lucky and spend a lot of time and discipline on it.) best ignore that one. I ignore any quests I need gems for to achieve it.
