Made these decks for league. They got me about an 80% winrate early in the last season, which was fun while it lasted. I hope you can make use of them.

Combines the horrible rng of DBH with the even worse rng of Debauchery - But with the right draw it can beat just about anything.
More than capable of 4ttw.

I'm told this build is unorthodox. Very fast though, once won in 3 turns!

Controly-breaker thing I play when I can't read the opponent. Adaptable, but not very fast.

Well known deck with a slightly unusual build. Lack of defence/healing bugs some people but I find it effective.

These two were used interchangeably, and I managed to always bring the wrong build for the job - SoD staves vs monoaether and firestall, momentastaves vs void-dials and OTKs. Their matchups are so different I reckon someone could get a good rating in league by just paying adrenastave mods, but I'm not that guy.

Not original but I highly recommend it.
Special mention to blarp's deckout meme and physsion's dark sopa wardens, which I also used regularly.
All other frequent decks were generic mono rushes, ghostmare, and pdials.
