I played in a no-show GPT, so we did casual round robin. 2-0-1 against UR Delver, BUG Delver, and DNT. I played 3x Swords which were crucial in the DNT matchup to fight against both Prelate and Mirran Crusader. I'm thinking of boarding them in while keeping the Chalice in too against Delver, simply because Chalice is either going to stick and win the game, or be countered/destroyed immediately.
On the SCG list:
Is mainboard Karakas necessary now? That list cuts the basic Swamp and, adds a third cycle land, and cuts to 5 fetchlands for an additional dual (Badlands). Only thing I can think of is against Depths.
Kolaghan's Command seems pretty decent right now, against DNT you can take out equipment and prelates, good against BUG (kill a Strix and a DRS), not so great against Eldrazi. It's a decent flex answer.
Tabernacle is something I've had success with too. Good against Pyro decks or to slow down Delver. I'm playing a Crop Rotation/Tabernacle/Bojuka Bog (main) combination.
