Lost to Sunyveil in the finals with this deck. I was pretty lucky with my pairings, 4 of the players i faced were on classic non-burn aggro, a matchup this deck feasts on thanks to the billions removals and Edict, and I won against an hooru control list with the best Adjudicator's Gavel of all time.
Jekk is completely absurd in that deck because it does everything FJS wants to do ; it clears the board, cycle your useless cards, is a huge threat that draws you cards and can be rebuyed by Display. Definetely expecting a nerf on that card.
The rest is pretty stock except for the Edicts that are a meta call against other Jekk decks, very happy about them, kills basically everything you care about and screws with void recursion. Winchest Merchant instead of the rakano one so your opponent has to have a sigil with jekk to kill it, and it's more robust against Salvo and Blightmoth.
Overall I'm pretty happy with that list, if I would change somethings i would probably put some cheeky 1-of to prevent the Turn to Seed highrolls.
The play experience was great, I love Jund with all my heart and I faced amazing players. Have fun with that list and a great day to you all !
