Her powers are pretty useful. She's got flight, superhuman speed, superhuman strength, the ability to grow, the ability to turn stone, and the power to animate and control the dead (or Wakandan dead at least). Her solo book established she has the ability to potentially draw on the powers of any previous Wakandan in history, so she may have more powers in addition to what we've already seen.
And she still has the access to tech if need be. We was using a good amount of that too in her solo book when she lost her powers.
