This list is not geared towards any one meta or particular playgroup because i'll be travelling a bit for the rest of 2017.

Hymn is fun and makes my pants tighter but I think the third copy should turn into the third L-Souls while I test lil' Giddy. He has been nothing but pretty solid. He's a lame-looking board staller of modular goodness usually but I've hardly lost if he sticks. That said, I bench him without rhyme or reason in MU's I haven't tested him against much to make sure he's doing work.

Any word on the 3-2 split of Hymn and L-Souls? I feel 2-3 split is probably right but didn't want to muddy the 3CMC slots with Gideon's sweaty muscles taking up temporary residence.

Considering cutting the fourth Extraction for maybe another C-Priest/another value threat (Spirit of Labyrinth, Crusader), another Brutality maybe?

Peace
