Thinking s'more about Moat Lurker. The Deathrattle is attached to Battlecry, so I assume it has to land the Battlecry otherwise the Deathrattle is 'void' or vacant in a sense. If you summon it via a portal for instance, it wouldn't be able to bring anything back. But also, the wording is 'Resummon', not a copy necessarily, which is why an enemy minion will be summoned for your opponent and not you. I wonder... if that wording applies to that specific Moat Lurker. Could you Moat Lurker a Moat Lurker which ate your own minion and get a double minion when the Moat Lurker dies a 2nd time or does it simply detach itself once dead. Likewise, would Faceless Manipulating your Moat Lurker bring a minion back twice? Faceless copies all damage and buffs, so the question is does the Battlecry/Deathrattle act like a text buff...
N'Zoth and Resurrect simply say summon, which is why when you get your minion back it is at full health. Maybe I'm drilling too much into the wording and Moat Lurker is simply piggybacking on those existing effects, but I'd be WAY more interested if it indeed had unique mechanics attached.
Fake Edit: And now that I think about it, the spell Ancestral Spirit does indeed say 'resummon' and works exactly the same. So you probably can't daisy chain them with buffs.
