DESCRIPTION
The lands in the sideboard are so you can transform into a counterspell heavy version. Typically you'd drop a Swamp, a Mountain and a Sulferous Springs for the land, then remove 2 Cruel Ultimatum, 2 Spitebellows, 4 Thoughtseize and 4 of whatever isn't helping you to have a full counter-build. I'm also considering a Faerie varient that uses Mistbinds to lock the opponent down the turn before casting the Ultimatum. Thoughts?
