As have many, I have been struggling with the rise of the various flavors of Hollowvine. Many of the traditional dredge hate cards are proven ineffective against the new menace. I wanted to get a thread started to discuss various strategies which have proven effective.
I'm mostly playing Jeskai Xerox, so my focus will be there, but I welcome discussion of other archtypes as well.
As many have realized Surgical Extraction backed up by Dreadhorde Arcanist is line of defense number 1. The old trump, Tabernacle is still effective, but not the game ender it used to be given the adoption of Gaea's Cradle in the U versions, and the mana'd version using Hogaak.
My current sideboard is as follows:
1 Mindbreak Trap
1 Lightning Bolt
2 Shattering Spree
1 Containment Priest
4 Surgical Extraction
3 Tabernacle at Pendral Veil
I'm thinking I need something in place of 1-2 of the Tabernacles as the opponents are aware of it and largely prepared.
