Most of the material here comes from sources other than myself. My hope is that this gathers a wealth of information from multiple sources and locations, brings it to one place, and presents it in an organized format.
Use Sliver Overlord, Homing Sliver, and tutors to pull specific cards from your library.

16 (Thorncaster Sliver or Acidic Sliver or Cautery Sliver) + Venom Sliver

25 Mana Echoes + Morophon, the Boundless + Sliver Overlord
Morophon, the Boundless lowers the cost of each Sliver by , so the only remaining costs to cast your Slivers are for the generic mana. You will need mana to kick off the onslaught. (Mana Echoes provides at least on the turn you play the second of Sliver Overlord or Morophon, the Boundless). Once Sliver Overlord and Morophon, the Boundless are in play. tutor for Crystalline Sliver (for protection) followed by all of the Slivers and Cloudshredder Sliver (for haste). Each of these will net positive mana from Mana Echoes as they come on to the battlefield which you can then use to pay the generic mana costs as you tutor out the rest of your hive.

+ a mana Sliver
your 3 Slivers for to use Sliver Overlord's ability to tutor for Crystalline Sliver (for protection).

Sliver Token Generation:
28 Bonescythe Sliver + Brood Sliver
Definition of the Combat Damage Step: "All creatures in combat deal combat damage at the same time, except when one or more creatures have first strike or double strike. In this case there are two damage assignment steps." With Double strike, you have two damage assignment steps when dealing combat damage to a target player, therefore you get one sliver token per damage assignment step. Work this concept into Combo #7/7a, and it potentially becomes a Queenless wincon by creating infinite Sliver tokens and infinite mana of any colour.
