i threw this together a few hours before registration so this exact build is a little rough but the overall strategy may have game against praxis pledge. i beat 3 praxis pledge in the top 8, but the matches were close (3-2, 3-1, 3-2). the idea was take popotito's 8merch, 8 fate, and 0 seek power tech into the dark heart shell... but then forgot to remove the seek powers, so you might be possible to trim a few. i also almost never casted Find the Way and it could probably be literally any card with echo.
praxis hates Vara, Vengeance-Seeker, and will sacrifice even large threats to shrink her. also Annihilate is the lifeblood of the deck, and your only proper answer to a turn 2 Amaran Stinger. try to reserve Desecrate for SST, moonstone, HOTV, or begrudgingly a Darya, Warrior Poet. and don't forget about the classic Torch + Heart of the Vault set-up.
otherwise, the name of the game is defense. praxis struggles to effectively remove larger threats outside of deadly, Shugo Standard, Xenan Initiation, Gunrunner set-ups, and going wide and large with Xenan Obelisk. try to position yourself into a board state where you can safely Xenan Temple killer one of your endurance units. if the temple ever finishes its agenda you've very likely won on the spot.
if you want a little more value/grindability, you might take tools from BruisedByGod's recent ECQ xenan mid - with some amount of either Dark Return or Mystic Ascendant.
another hedge between grindability and defensibility would be Ayan, the Abductor - as it would probably improve the hooru control matchup as well.
finally, if you wanted more cheap removal Banish/Casualties of the Cause might be an option (but i'm not wild about either) or if you think you had the time to sift through cards there's always Quarry
BTW how do you feel about the hooru control match up? I've been having some helpless games where they remove everything until a chain lands and that's game over.
oh - yeah hooru is probably an autoloss. this deck is very much big slow midrange and theirs is very much big sweepers and slow removal which lines up perfectly to fight this kind of play. like, i think the deck would need a massive retooling to fight hooru because you simply can't outgrind hooru unless you're temporal.
