This is a mill deck. Your objective is to exhaust your opponents deck.
To use this deck to do so, you'll want to time Harbinger of the Lost, Crystal Shards, Wave Collapse and Praxix to make the most of Reverberate.
You have ample draw here in the form of allies (Falseblood Cultist) and items (Crystal Shards).
Knowing what not to sacrifice is important. Never sac both Soul Reaper, or All Hope is Lost. Try not to sacrifice allies if you can help it. Skip sacrificing is sometimes okay, because you're aiming for around a max of 8-10 resources. Any more than that is excessive.
You'll want to take a beating early on. Seriously. Let your opponent waste as many cards on you and your allies as possible. Dont go throwing Wave Collapse on just anything. Save them just in case your opponent actually managed to get their fattie in their hand. Time your discards to make the most of Reverberate, while digging for a Soul Reaper.
Once you can no longer take the heat off Praxix, and you are certain your opponent can finish you next turn and there is nothing else you can do about it, pop Soul Reaper. By this time, both decks should be in the low teens or single digits.
From here, All hope is lost is your heavy hitter. At 8 resources, you can deal 40 damage by rotating these cards if your opponents deck is empty.
A few words
I've tinkered around with Praxix since his release, and have tried many different combinations using support from Shattered Fates. Notably, a few of those cards have been mentioned below but Reverberate really shined during play testing. It accelerated the ability to discard the opponents deck without drawing to much attention from the opposition (probably due to its duration).
Redux Channel, although allowing for awesome combinations with Transference and Praxix, proved to be to situational because of the possibility of encountering solo and/or semi-solo decks. It also proved itself to be counterintuitive even when facing ally dependent decks. This would be a much better card if it allowed you to target your own grave, but that would be a little op in this deck for the cost.
Energy Extraction is amazing. Allowing you to deal damage to the hero while dumping your allies for heal potential, but the additional cost proved to stall the overall objective of milling by slowing down Praxix. If the additional SE cost had been replaced by a deck discard instead, this card would be golden.
Living Armor is very versitile and really has the ability to quickly get you out of almost any nasty pinch, but then becomes top priority for you opponent next turn, and is usually dealt with quite easily. It does discard but from your hand, which can be useful sometimes but this card is so expensive it hurts.
Dagger of Fate is great if going for an agro build, but beating up on anything isn't the overall objective of this deck.
Note
Do not make the mistake of thinking that Falseblood Cultist will activate Reverberate. Remember that Reverberate will only trigger if a card has been discarded from your deck, not your hand.
Do not worry if both Soul Reaper have hit your grave. Remember that Soul Reaper has a casting cost of 3cc, and therefore can be targeted by Mimic.
Do not sacrifice Eternal Renewal when facing an 80+ card deck. Eternal Renewal is here to allow you to mill larger decks. So, in a sense, this can become a possible 100 card deck, allowing you to reuse your ammunition for a 'second round'. Make sure to keep track of your sacrifices when playing this card. You don't want to get stuck attempting to dig for a card only to realize that it isn't there because you've sacrificed it early on.
