My first idea is to play discard on mainboard and be more focused on the combo. We can't grind decks with JTMS and now Jund is harder to grind because BBE so focus on the combo could be a good option. Tidehollow Sculler isn't the best against Jund but there is a lot of cards in the sideboard to change them. You also can change the Rhonas the Indomitable for a Spellskite if you want to have some Mainboard protection against removal.
Other option that comes to my mind is to play mainboard 3 or 4 Voice of Resurgence in mainboard instead of Tidehollow Sculler. Voice of resurgence is a great card against JTMS decks and is an ok card against Jund and also makes Eldritch Evolution from sideboard a better value card. We also can add a Scavenging Ooze in sideboard or mainboard if we want graveyard hate.
What do you think guys? Lets test some new builds before we abandon this great and beautiful deck!
