This is the current praxis tokens deck I use to grind ladder. it started out as the budget build from an article by sunyveil on eternal titans (https://eternalwarcry.com/decks/d/uJUTjQc4H_c/praxis-tokens-11-9), but as I have gained more cards and shiftstone I have made some adjustments to it.
It is still very budget friendly, the main deck contains no legendaries, however the market does contain some legenedaries, mostly ones I have aquired from campaigns or packs so feel free to change these up if needed.
The general aim is to go wide on your opponent and then use
Rally or
Talir's Choice to get in for lethal. there are some hands that can be explosively fast with turn 4-5 kills, however there are some other options for the late game if things go long, including
Arcanum Monitor to force through damage and gnash in the market to help clear games and generate tokens.
Your first merchant should nearly always be used to get
Xenan Obelisk, with your second merchant being used more reactively depending on the board state.
For removal you have access to torch and purify as well as scorpion wasp, it does feel expensive for a token deck, but wihout a doubt it has saved me and allowed me to deal with larger threats. In most cases I am keeping this is hand until I can ambush a larger threat and get the most value from it, but occasionaly being played at the end of turn can mean you get in for lethal next turn.
As always suggestions appreciated.
