AntiVector's 1-2-3

This deck accepts the fact the Praxis Trove never gets charged above 3, so treats it as a pseudo-site that only dies to relic hate.
With limited spells in the deck, consistent results can be applied.

Things to note:

Kato's Totemite costs 1: Both Kato, Arena Herald and Assembly Line produce 1-cost minions, alleviating the problem of redundant Troves thirsty for a 1-drop.
Moldermuck+Vine Grafter: Giving Moldermuck regen with Vine Grafter allows it to survive its first self-damage unscathed (though without the shield on the copy) Don't forget to attack with it if you're looking for a 3-cost!
Toll of Warfare: Toll of Warfare is mostly for games that manage to sweep or otherwise drag for so long that one of your Troves actually gets to 4. Use Wasteland Broker to bring it out. Also, Broker cannot bring out any 4-cost cards he shuffles in due to Trove activating first. Might replace this whole engine in the future.
Shrine to Karvet: While not strictly necessary for this deck, Shrine to Karvet is quite effective here since every 1-drop essentially comes with a free sacrifice. Urgent Missive was put in due to running out of Combust, but between drawing and Troves, you'll rarely be wanting for removal.
