Factory was incredible, not going to use btb. Counterspell was ok, it was always relevant and always castable. I feel like without forces I need some sort of unconditional counterspell. Two felt correct. I do agree on more spell snares, will definitely cut a pierce for a snare.

Tnn I'm thinking about. Obstructionist stifles things while under standstill and has flash. I will probably cut to only 1 copy. That slot will be taken up by trickbind. Then I'm thinking I might cut a vapor snag for a piracy charm. Islandwalk seems very good and it can kill small creatures without costing me 4 life. Giving a small amount of reach with delver/dread/factory is relevant. Also, cage was lackluster. It did nothing against cabal therapy or life from the loam. Straight out for surgicals.

An all-star out of the board was sower of temptation. Super hot tech.

So:
-1 spell pierce
+1 spell snare

-1 nimble obstructionist
+1 trickbind

-1 vapor snag
+1 piracy charm
