Nim Devourer can be pretty useful. Turn a crappy token into an average threat, or just return him and sac him multiple times per upkeep to trigger Teysa, Grave Pact, and Soul Warden.
Target Grimgrin. Tap to bounce something. Sac a guy to untap Grimgrin. Tap to bounce something. Repeat as desired. Meanwhile, Grimgrin is growing the whole time.
I am the archenemy facing four opponents. I control Luminarch Ascension. During my opponents' turn, I do not lose any life. During the end step, the Ascension triggers for each of my opponents, resulting in four quest counters. Is this accurate?
Strategy:
This deck should be played as a control deck. Grind your opponent(s) down with removal and establish card advantage with the ETB and LTB effects of your creatures. After the first few exchanges, use Karador rebuy your monsters and start laying into your opponent(s). This deck can win without Karador ever being cast, especially against weaker opponents or favorable matchups. However, the deck is designed from the standpoint of having him available, so be prepared to defend Karador from tuck or mind control effects by sacrificing him to another creature or land in response, when possible.
Requiem Angel is a great token generator. Not only does it make its own, but it can get you double mileage out of most of your other tokens as well.
Dawn of the Dead can be pretty good too. Return a creature with a ETB effect, then sac it for an additional effect and dodge the exile trigger.
Dimir House Guard is mediocre tutor that also works as a sac outlet.
Endless Cockroaches is another recurable sacrifice target.
Martyr's Bond and Reaper from the Abyss are functionally similar to Grave Pact.
Necrotic Sliver isn't Vindicate, but it triggers Teysa and Grave Pact.
Mentor of the Meek is a must for tokens.
Mortarpod is another great sac outlet.

New version has more card advantage and more removal.
Yavimaya Enchantress seems good. Auras than recur themselves should be a priority. Retether as a one- or two-of can be insane.

Spreading Plague
Grimgrin gets the ability. After knack resolves he reads:
Tap: bounce a non land permanent.
Sac a creature: untap & +1/+1 counter.
Whenever Grimgrin attacks, destroy a creature & +1/+1 counter.
As long as you have the creatures to untap him, he can keep bouncing things.
Target Grimgrin. Tap to bounce something. Sac a guy to untap Grimgrin. Tap to bounce something. Repeat as desired. Meanwhile, Grimgrin is growing the whole time.
