I've seen Raphael Levy's posts regarding Life from the Loam attempts, and I like the synergy between Haakon, Knight of the Reliquary, and Life from the Loam.
I've read other posts over the weeks, and I will cite them if I can find them, they planted the seed, and this is the strange baby it grew.
Nameless Inversion, a card I had never even heard of, does a lot of work here. My other deck, Death from the Loam, focused on Primal Command being able to synergize with creatures as a toolbox, utilizing Life from the Loam and Smallpox/Death cloud to eventually lock out your opponent. This takes it a different way, with multiple engines, and keeping the creatures "Knight" specific (the exception being Eternal Witness) gives it a certain Hatebears feeling, with protections from removal centric colors making them durable.
Haakon himself can get around RFG effects by having two mana open and casting Nameless Inversion (It's a Knight!) from the graveyard, targeting Haakon himself. Inversion itself can be recurred targeting your opponents creatures and locking them out.
Life from the Loam works with Smallpox keeping you ahead of the trade. It also works by dredging more lands into the yard, making Knight of the Reliquary bigger and bigger. Haakon keeps the Knight around, even if he dies. Loam also feeds Raven's Crime, allowing you to strip their hand repeatedly. You can also use it to recur Ghost Quarter, fetches, or Bojuka Bog for abuse. Combined with fetches, the thinning was so real, I added a singleton Goblin Charbelcher for a bit of laughs, but ultimately it couldn't stay.
Deathcloud itself can be used nearly without fear to wipe out your opponent completely if you can't get an engine going, or they simply get ahead of you. Everything you dump into the yard can be fetched back.
The two one-of knights can be tutored with Primal Command, and if accidentally dredged, Haakon fetches them no problem. They are to help hedge against Burn and Abzan/Junk/Zoo.
Primal Command gains life vs Burn, bounces a land or critter to the top of it's owners library, forces a graveyard to library shuffle (can also protect you vs mill, if that's a thing you ever see..) and, most importantly, fetches a critter out of your library.
Profane Command can act as a bad Fireball, brings back an Eternal Witness (thus bringing something else back!), kills a critter, and, rarely, can give your team Fear to swing through some non-black, non-artifact dudes.
Erebos: Not a knight, but a creature everywhere but in play. Gives card draw, stops lifegain, survives all of your sacrifice shenanigans if you stack things correctly, and.. rarely.. sometimes.. you can get both Haakon and Phyrexian Crusader out for devotion, and swing with Erebos. If, in magical Christmas land, this should happen, you can also, because Haakon is out, cast Nameless Inversion AS A BUFF for Erebos. Even twice, since this is Christmas Land, after all. I wouldn't even try it unless your opponent is Hellbent, or you could eat a Path or Dismember, but it is an interaction to be aware of.
The manabase is a mess currently. Dakmor Salvage is in to help get the dredge going to find your pieces, Ghost Quarter will lock them, eventually, and hold down scary manlands in the meantime, and Bojuka Bog is a maindeck answer for Delve and recursion based decks.
Speaking of manabases.. The scariest card against you is Blood Moon. You have the answers for it, but if your non-basics are all you have, and they catch you tapped out, you're gonna have a bad time.
Graveyard hate can also be an issue, with Grafdiggers Cage, Relic of Progenitus, Scavenging Ooze, etc, running around. Your defense is in the sideboard, with Leyline of Sanctity.. which is also strong versus burn and some combo decks. Creatures you can kill, wholesale if need be. It's the other card types that can ruin your day. Be aware of them.
Counterspells are, for once, not a weakness. Delver or Merfolk may be able to catch a couple of early spells to out-tempo you, but resolving an early smallpox, or getting an engine going early, gets you out of danger. Countered just keeps it away for the current turn.. you will get another cast. Also, Thrun, good versus control AND Burn.
