This is the results of my deckbuilding of the last few days: a midrange feln deck with controllish elements.
In no way this is a refined deck. I don't play a lot and this is only the result of my testing. Feel free to improve the deck and give suggestion.
Yet the deck work! I peaked at rank 2 masters and now I am rank 4, so there must be something good in there. The matchup vs aggro is pretty bad, but you beat argenport midrange, and that is a big plus.
Things I think this deck does good, for future feln midrange deckbuilder:
No 2 drops: - too low impact in slow matchup, which you are supposed to dominate.
Impending doom: - way better than steward of the past in current meta,
Midninght gale: - card is really, really good. usually eats a vanquish, but it clear the way for your gamewinning 4 drops.
The deck is super expensive in terms of vials.
To budgetize:
-2 jotun +1 impending doom, + 1 steward of the past
-3 rindra +3 steward
-1 black sky and -1 vara +1 strategize + 1 feeding time
Other legendaries are core.
Any question I will answer in the comments.
Thanks for reading and enjoy!
One thing I noticed though is that Strategize felt awkward in many situations. There was rarely any card I really wanted to give up. If you say this deck is weak vs. aggro (which I only encountered one time today), I would like to know whether you considered Nocturnal Observer instead of Strategize for this deck? It can act as draw/discard or as a blocker against aggro depending on the match-up (and also keeps Rindra, the Duskblade activated).
I would say that maybe a mix of this and reanimator with it would be good, but I have not been able to make it work, yet! ;)
