yea it's gotta be healbot, lightbomb, loatheb, or belcher. prolly not belcher tho cuz it literally enables nzoth decks for every class.
i've played a bit of that control warr list card for card -1 ichor +sylv, it's definitely strong, but it's scary sometimes to play it because you end up answering literally every card in the opponent's deck so fucking often. i beat a midshaman where at one point i literally was just removing all of his topdecks until i pulled an ironforge portal and started beating his face with a tomb pillager. like the threat density is non-existent because you're playing the elise game, but it's even more non-existent than older elise warrior lists because you're playing the elise + yogg game where you're going absolutely balls out full removal. but there's no way to get around it in such a list because the more threats you add, the weaker the overall strategy gets.
basically what i'm saying is that the deck is strong and the main thing i have against it isn't necessarily even a game-deciding bad thing when it pops up.
