Considering replacing at least one squidface with a corrupted healbot. Also don't have Xaril. Thoughts, please?

If N'Zoth, the Corruptor is your win condition, what happens if you play it and your opponent clears your board? At best you're left with a 5/5 if you managed to play Twilight Summoner earlier.

I would consider Shadowstep. You also don't have much in the way of card draw.

While I loved Journey Below at first for its versatility and being a turn one drop option, overall I found its space is better filled with other, more consistent options. I would not run Twilight Summoner. Being an overall 4 mana for 6/6 worth of stats is nice, but the card is way too slow. Admittedly it is the best target for Raptor, but still too slow. Anyone that knows the meta who sees a Rogue playing Twilight Summoner is going to pop it asap, as they know the Rogue player will want to follow it up with a Raptor to clone the ability. I would also replace the Squidfaces. Not a bad card, but just not good enough.

Here is my own list if you want to compare. A card I actually advise putting in N'Zoth decks for Standard is Infested Tauren. Having Taunt on a Deathrattle card is huge for N'Zoth, while still allowing you to swarm the field and not die the following turn. (or helping in that, anyway)

It's cute but one dimensional, I would throw away these epics for some legendaries. It doesn't have to be all deathrattle deck to be viable with N'zoth.
