Argenport era endet - Feln Control

Argenport is still dominating the meta. Midrange, fliers, aggro, control and combo decks.
But Feln ever was in my mind as a good Control Deck, even with the Vara nerv the Crests gave it a comeback.
But what will happen with the meta and what will happen with Feln Control is this new set?
I do not know, I just looked up the new cards and now I am playing this deck on the ladder.

Tell me your suggestions. Which card could be exchanged? I finish my games most times against Midrange or Aggro with the units. Channel the Tempest mostly kills units but is the win condition against other control decks.
