For Healing moves, in generation 8, Vespiquen only has rest, by tm, but if you want a sweeper, being asleep isn’t too useful. To raise Defense, so It doesn’t get that low in the first place, there is Defense Order, as well as aromatic mist, and Vespiquen’s defences are pretty high in the first place. Other that that, that’s it. I’m not into competitive, so idk if these are legal.
