Mill Combination (EDH / Commander)

This deck has 6 main combo wins, and there are 98 ways to achieve these 6 combos

I love combos! Back in late 90's and early 2000's, me and my brother had countless battles, who can combo first, his saproling burst deck or my Traumatize/Guiltfeeder deck?
When I discovered commander late last year, I was determined to build my Traumatize/Guiltfeeder commander deck in commander, and have spent countless hours making this deck work.
Sadly, neither Trauamtize or Guiltfeeder ended up making the final cut.
Here are the game-winning combos

Game ending combo

1. Grindstone/Painter's Servant
2. Mindcrank/Duskmantle Guildmage
3. Bloodchief Ascension / Maddening Cacophoney
4. Maddening Cacophoney / Bruvac the Grandiloquent
5. Syr Konrad the Grim/ Maddening Cacophoney
6. Psychic Corrosion / Peer into the Abyss (targeting yourself)

I should get bonus points for excluding Thoracle/Demonic Consultation !!! O:
I am tutoring for these combo's, so the amount of cards that actually allow me to combo is something like this
(I realize this is a stretch, but its actually how the deck operates)

Vampiric tutor/Grindstone
Vampiric tutor/Painter's Servant
Vampiric tutor/ Mindcrank
and so forth, and so on, with the following tutors

Vampiric tutor combos with 10 cards
Demonic tutor x10
Mystical tutor x 8
Varragoth Bloodsky sire x10
Liliana Vess x10
Disciple of Deceit x4
Tezzeret the Seeker x4
Grim Tutor x10
Diabolic Revelation - allows me to get both sides of the combo, x6 for both, x10 for 1
Diabolic Tutor x10

So the total amount of two card combinations that win the game is 98!!
