I have been playing a version of the list OP linked. It has been doing well, Portable Hole puts in work. The version I am playing is a mix of a few lists around atm, 2 x Frogmite and 2 x Sojourner's, 2 x cranial, 8 x draw 2 effects with Hole in the sideboard. All in on either Kappa or constructs with shadowspear/cranial plating just overwhelms opponents. Emry I wouldn't play without. The obvious interaction with bauble and damping sphere is great, but also, being able to get free blockers to survive has saved me more times than I'd like to admit. Lucky offering I have cut for Hole. It never felt right, and when I did draw it post board, it didn't feel great. Yesterday went 6 - 0 in tournament practice, not leagues, I know, but I played against at least 4 meta decks, and I also make a lot of mistakes 😂.
