Well that opens additional questions
Was it subjectively or morally agreeable? Morally is the imperative here
Objection feels damn good when it wins you the game xD It sounds symmetrical to me 
Besides, you can build your deck to play against it but putting bait-minions in the deck for such cases
You can’t build your deck around a guy, I don’t know, drawing a card on turn 3 that plays a card which costs 4 which draws Ceaseless Expanse and deals 125 dmg to enemy face
I mean, it sounds very much to me like I bought a lottery ticket costing me matchmaking time where i just drew the “unlucky” straw, lost some ranks and have to hit matchmaking again hoping to find an actual game
Closest to that I remember from Standard was Nature Shaman last year, and I sure as hell abused it for as long as I could. I understand morality and I’m not letting myself get ran over unless I want to for some reason, which I usually don’t.
