What are your best accidental healing powers?

Naturally when it comes to generating conflict, healing isn’t at the top of the list when it comes to options in most narrative formats. || and in this case with the shard network || So like Bonesaw can choose to heal but whose primary intention is modification similar to Amy, what sort of powers could you use where healing is a side effect?

One rather interesting idea I remember discussing was a time striker power where you could drastically accelerate or unwind temporal affects of things which can cause you to reverse the time of people and objects to before they were damaged or accelerate time on a wounded target to make the wounds worse via rapid infection.
