Wake up already

2nd iteration of my Nightfall Feln build after many games.

What changed:
Affliction seems bad but grants early interaction and may enable important trades against bolder decks, also early enabler for Miris Nightshade.
Sabotage does well and by far better than the new 1 drop Unseen Sinister Opportunist.
Vara's Intervention is better than Levitate in that we can replay some Unseens as well as interact with aggro and enable trades, it can get even your last 2 damage with Nocturnal Observer in after the momentum has already swung. This is important because sometimes you just ping your opponent to death and this card can be an important finisher.
Winter's Song seems like a really bad Permafrost but with the Nightfall ability we actually want it, it does work.
Daring Pioneer feels really good after a Sabotage and even better if another unit already got removed. If you curve into Rindra, the Duskblade you will feel good. You will feel even better if you can put a Dueling Pistols on him next turn, that's why these are +1.
More Common Cause because you actually have explorers in here too.

Besides what stayed I can not say how important Nocturnal Observer is. If you try to pressure your opponent you can often find an Amethyst Waystone or a Curse that just cripples an enemy enough to force him to act in your favor.
Maybe the deck only works because after Dusk Road release people durdle around, but you can steer your way through tough games with this. It is fun and not too bad imo. Nevertheless I appreciate ideas for improvement.

As of 20-30 games winrate is marginally better than 50%.
