Xenan Grinder (Killer/Mill Wisps)

Since my collection is still rather small, I made this cheap(ish) nightmare of a deck.

The game plan is simple:

Early Game:
Give Pathlighter and Nocturnal Creeper killer effects(preferably pathlighter for recursion options). OR Start abusing Spitefeeder right away. Dreamsnatcher being on board is a plus, as you'll always be milling your opponent. If you get Pathlighter's reduction effect off on Dreamsnatcher, it makes him a valid target for Shadowlands Guide which can create some ugly auto wins if the game drags on.

Mid Game:
Keep your opponent's board manageable by recurring your deadly/killer wisps. Don't over commit to the board. Try to use Devours wisely, and don't be afraid to stall out with chump wisps. Getting Azindel down at this stage of the game is where shenanigans happens, as every killer attack is +2 Maximum power. Unless your opponent nukes the field, Azindel tends to stick around if he's not on block duty. Save Memory Dredger for as late as you can cast it. If you play it early, it's guaranteed to do nothing but eat a removal.

Late game:
Keep your opponent's void in mind. Depending on what cards spitefeeder has hit early in the game, your opppnent might be low on bombs and removal, while you're often able to recur a card or two. Memory Dredger against an opponent with no removal and no enemy flyers is essentially victory.
If Azindel has stuck around at all, Dreamsnatchers are an autocast mill 15, if your opponent has a board at this stage, Dreamsnatchers can swing fearlessly with a Dredger on board, as no one really wants to get hit in the face with a 13-15/3 Lifesteal unit. If Dredger gets through, it can revive a blocked Dreamsnatcher, and you can use it's mill, again.

I've had 4 ragequits against me, today alone.

Token decks can autowin against this deck if obelisk comes down early. I might swap Eremot, the Gathering Dark in instead of Azindel Revealed for the market if I run into a lot of removal piles. As long as you don't commit too much to the board, Harsh Rule isn't a big problem, especially if you mill any of them(or anything useful really)
You'll rarely ever play big Azindel in this deck anyway. it's usually safe to pull The End is Near out of the market at 6-8 power. Guaranteed gas for the rest of the game helps this deck a lot.
Solitude and Umbren Occluder are obvious market choices if you have them.
