You can make the package much smaller.
1x Azami, Lady of Scrolls
4x Narco
1x Angel of Glory's Rise
1x Lab Maniac
This is sufficient to win immediately if you mill your whole deck. Azami lets you tap herself and Maniac for the draw you need.
Don't you still need dread return for this? Not sure how this package is smaller than 4 narco, 1 sutured ghoul, 1 dread return, 1 lord of extinction, 1 dragon breath - that's 8 cards, and if you need to dread return the angel, you're still looking at 8 cards. With the ghoul combo, if they somehow shut off your grave recursion (grafdiggers cage anyone?) you can still power through an LoE for 5 mana and have a massive beater. I guess you can hardcast maniac and mill for the win, but then you're really vulnerable to instants like bolt/bounce. With worldly tutors, you can grab the LoE too, which you just have to slow draw the maniac. I always play with tinker BSC as well so that 1) you can mill the deck on upkeep under a tangle wire and still win, and 2) you can just drop dual, crypt, tinker with insane counter backup to just win that way. But BSC is not so good with maniac. At any rate, I tried a similar list, updated from my old version - and while it consistantly goldfishes on turn 2 FTW, it is ridiculously fragile. Magus of Moon, extirpate, any dredge hate, darkblast, pithing needle, revoker, lightning bolt, fire/ice, any spheres, chalice....all things that really just suck the wind out of your day. My deck ran 4 misstep, 4 FoW, 2 daze, 4 therapy, 1 etruth, 1 claim MAINDECK - and it's still not enough. For reference:

It's retarded fast and consistent without an opponent - but against anything packing hate of any type, and you get rolled. I also use 2 bridges over 4 narco because you net more creatures to therapy/return with bridges, and it stops the opponent from ruining your combo by killing narcos with an instant in response to narco triggers to put you under 3 critters.
