It really shows just how much his time in the carnival's changed Strange that he honestly considers necromancy for a moment. But no, if he did that, all they'd have on their hands were shambling corpses that he couldn't really control or kill.

"I can only revive the dead, not control them. Besides, I don't have my dagger on me."

But ah. Those shards. Strange stands up, remaining in the healing circle as he does so. "The shards are a gift from the Silver Mirror. My bones, organs, and some of my muscles are covered in them, much like my scars." And before Syrlya can say anything, Strange continues talking. "You can chastise me about this later. Right now, we don't have the time."
