Feln Jarral (83:19 from bronze 3 to rank 3)

I haven't played throne in a long time, so I had to start from bronze 3 again and I decided to give Feln Jarral a try because it's one of my old favourites. The deck did way better than I expected though and I had a lot of fun, so I just played it for the whole climb and reached master after 4 days of excessive playing (51:6 from bronze to diamond, 32:13 from diamond to master). The decklist almost never changed, except for some adjustments to make the deck less clunky because I started losing to aggro in diamond.
Early removal in the maindeck, cheap efficient units (some of which have aegis) and cheap interaction in the market make the deck very resilient against aggro. The cheap removal also helps to slow down decks with time ramp dorks like Initiate of the Sands, which I saw surprisingly often. Dangerous Gambit is a great new card that works well against aggro (because you usually wont take a lot of damage if you kill their units) and those midrange decks (because you can either kill their ramp dorks to slow them down and take barely any damage, or their big units and take some damage, but get rewarded with a huge tempo swing in your favor). It also has the upside of being a Grenahen hit.
The high amount of aegis units and card selection (Grenahen, market access, plunder) also makes the deck good against most control decks. You can play around board wipes with a mix of ageis and non-aegis units, you can break face aegis easily against Hooru with cards like Serpent Hive, Through The Unknown and Trick Throw and then get rid of their important cards with Ziat, Steelwarren Reeve and you have face aegis and a market counterspell in Obstructive Flicker yourself to counter Equalize. Those + your early threats also help a lot against combo decks.
The one matchup I struggled with the most is Sylscar (Stonescar with a heavy shadow focus) because that deck can have more explosive plays and still outgrind you with Tasbu, the Forbidden. The matchup is far from unwinnable, but definitely unfavoured for Feln Jarral and I am not quite sure how to make it better without making other matchups significantly worse.

Edit: The Primal Symbol can probably be cut at this point, I just played it at the start because I played Helio, the Skywinder in the market. With just Jarrall Ascending as real payoff it's probably not good enough and you could play another feln dual power (like Tome or Banner) instead.
