I made some tests with
collective brutality in place of my 2 maindeck thoughtseize
Against creature decks it's very good : being able to kill deathrite shaman / white creatures / elves / delvers + sometimes extra discard against counters is good.
But against other decks it's weak and/or slow. So maybe it's more of a sideboard card ?
Now I would like to test gitaxian probe in that slots.
It looks good to know if the way if free to combo + great interaction with cabal therapy.
I've never seen the card in decklists playing recruiters/therapy version, has anyone tested that ?
