I was missing smashing face for 64 lifesteal in the first few turns, so here is another glass cannon Purifier deck.
There is a lot of redundancy here, and a lot of experimental cards, hopefully this set up doesn't tell your opponent what you are on, don't be afraid to cast protect against Exploit or any kind of discard
You are looking for a hand with 2-3 power or some fetch, purifier, a way into the market, and a way to protect purifier. then you want a way to give purifier charge or overwhelm depending on what your opponent is doing. If you have multiple purifiers early, don't be afraid to play one, you might win off of it. If you drop an early one, try to keep protection up for them anyway. You really want to get Reap ASAP and swing.
Pause for reflections to help bounce early blockers or save your purifier from nonsense
Time etchings to make sure you can get power and market access for Reap
Desert Marshall for early clears
Dissociate for pesky removal or early attachments
Porcelain mask to stop pesky effects and give Purifier overwhelm
Protect for your own hand or Purifier
Grafter to give Purifier charge mainly, and grab Reap.
Merchant for ramp, and more access to Reap
Ascendant for some lifesteal, chump block and relic removal
Purifier is the ideal wincon, give them Charge and or Overwhelm, hopefully drop an influence or two and Reap victory.
Evacuation Plan is an idea in testing, IF you somehow don't kill them with purifier on the kill turn, put them back in your hand and replace them with a huge Sentinel, or another expensive way to protect Purifier in general.
Praxis Arcanum is another way to give Purifier Charge, and makes everything cheaper.
The market
Reap - Your win con card essentially
Infinite Hourglass to fight stuns
Predators Instinct to overcome ridiculous board states with Purifier
Privilege of Nobility against discard
Sword of Unity is probably a flex slot, but gives Purifier (or whoever) an edge.
