Unstable Feln

Throne Deck By


Cost Curve




This is the deck that I played in the Spring Throne Championship this weekend. I didn't do well, but several other people got the deck from me and made T64 (including mgallop making T4), and I thought I'd post it myself and write a few words about it.

The deck is fairly difficult to play because it has a lot of card selection (Strategize, Smuggler, Sprite, Honor) and a lot of cards that vary in value depending on circumstances or can be used in many different ways. Unstable is the most obvious of those - it's an echo card to put back or discard with Strat/Smuggler/Sprite/Honor, or you can use it to try to upgrade your own units (Felrauk is the best target, but also using it on Blightmoth Shade, Smuggler, or Cloudsnakes from Mother of Skies can be good), or you can use it to try to downgrade opposing units. You also have a lot of cheap cards along with Lightning Sprite, so you often get to do multiple things in a turn and thus have many options each turn.

Possibly the part of the deck that I'm most proud of is the Transpose/Silverblade Menace combo in the market. It isn't a secret that Silverblade Menace is a good market card, but having the option to market for Transpose and then use the Transpose to market for Menace takes it to another level. If you are trying to burn your opponent out with Menace, this effectively means that your Menace either ignores faegis or does 2 extra damage, while if you are trying to stabilize against enemy burn with Menace, this means that your Menace comes with faegis.

Hello, thanks for the deck. I've been looking for a Feln deck that's not heavy control and yours seems very cool. Do you think it's wise to replace Seek Power with Suffocate (if we're meeting a lot of Aggro) or Sabotage?
BillCosbatron Eternal Version: 20.05.15
Not the deck creator, but if you find yourself going up against aggro (Sunnyveil's decklist probably) I don't think you wan't to replace seek seeing as you need 3/3 influence for free felrauk or it's a dead card early on when it's Important to get it out early to block and while the opponent has cards in hand, and the 5primal is important for having a 5/5 body with aegis to block without it dying to torch/sear,so i'd replace 2x honour the claws with suffocate, personally. Also maybe replace the turn to seed in market for malediction which doesn't kill your own 4 health minions, which is very relevant.

Forgot to add, the 5primal influence for Champion also gives it flying to block Thunder of Wings and Phoenix Stone. So definitely keep the seek powers
