The Top End

 I ended up adding both Faerie Formation and Psychosis Crawler to the deck to see if either one of them was clearly superior. 

But it turns out both of them fit the Hexdrinker rule* and neither one of them seemed to out Hexdrinker the other: my opponents didn't want me to have either card. 

*(If you're new, the Hexdrinker rule says that if I'm testing a card and when I play it, my opponents go 'oh no', then I should 100% keep that card).

I also retooled the low end threats to have a faeries bent. So now Faerie Vandal and Scion of Oona join Hypnotic Sprite. 

The Faerie Vandal could become a legit threat over time and since this deck does move to get to midgame, I'm hoping it'll pay off, but the initial tests haven't given me enough data. I'm going to keep running them for now, because I think the opportunity for them to get beefy relatively quickly is there and every threat needs an answer.

There was a game where my opponent played 5 board sweepers. She was running 7 total. There's not much I can do there. But most decks don't go that far, hell, most decks don't even run Wrath effects anymore. So I'm still feeling good about the direction I'm going in.
