This is the primal version of the Praxis trove Shared destiny combo that I already mentioned in the other guide. It feels more consistent and also better in the few turns leading up to the combo, but it is still work in progress, so play it at your own risk..
The combo is pretty much the same like in the other version (https://eternalwarcry.com/decks/d/oc0OUY0iWmE/praxis-trove-destiny-combo), but instead of Fire etching for First flame we play Primal etching for Decimation. Turn to Seed can kill the few existing hard counters (
Katra, The First Seal and
Tocas, Waystone Harvester) except for
Adjudicator's Gavel, but few people are playing Gavel and the deck has 8 face aegis to play around it. Hand hate and counter spells can counter the deck to, but face aegis can counter hand hate and counterspells are rarely played. I still lost a few games to those kind of hate effects, but not nearly as often as I expected ( I am at about 50% winrate, but many losses were due to me playing poorly and due to the list still being a work in progress). Try to keep an eye on the cost of the units in your hand (e.g. dont play a 1 or 2 drop out in the early game if they are your only unit of that cost, except for if its absolutely necessary).
Good luck and have fun!
Edit: Kato and Mother got cut because of the screw up potential. Shepherd does the same thing Kato does without the potential for screwing you up and Tripwire Grenadin is a flex spot, meaning it could be any 2 drop you like (Tripwire helps against hyper aggressive decks with many X/1s and Rakano).

1) Kato's Corrupted Shade costs 2, so if you played Kato somewhere early, then Praxis Trove and a 1 power unit, Kato might screw your plan by dying on the opponent's turn.
2) Mother of Skies summons a 1 power unit, so after Praxis Trove you might accidentally start your chain by playing Howling Peak Smuggler.
3) Kato summons a 1 power 0/1, so don't play him after Praxis Trove until you are ready to go off (lacking 4P influence, for example)
4) Sometimes Shared Vision will come out off the top after shuffling it on the preparation turn. Don't be spooked, but do keep in mind that you its effect is forced, i. e. you might exhaust all of your blockers. Normally blockers aren't needed as you'd draw Prodigious Sorcery from the Market, so on the Decimation turn you immediately reuse it. However, sometimes you have to play Nocturnal Observer on your prep turn, thus lacking ways to close down the game right away; then you have to chump block to stay alive.
Deck
Using Aid of the Hooru over Decimation because it feels a bit better at stabilizing when you're behind. I also run Time, because I really wanted access to 12 Fire merchants to ensure you can get trove, plus you get to run Excavate just in case you need to Aid three times. Cleansing Rain is probably a bit too cute, but it does trigger from the Owls from Aid and it's only one slot, so it's staying for now.
