@Merppity it's auto repair is fast enough to full repair from partial annihilation and state not unlike diced onions in under 24 hours. It could probably just put a severed limb back on. That said, I don't think you're wrong.
Blade lost because he prequeued his strongest available attacks so he could Max smack anything more times than normal, and then panicked when that was no longer a viable option. He probably could have forced a draw otherwise.
@daxrocket I may be misremembering, but in one of the rare serious moments I think Blade talked/remembered about having comrades before and constantly losing them. Unless I am losing my mind and it's a different hero manga that I am remembering.
