I say it’s not good at the moment. Everything is random, you don’t get to pick. In the current meta, aggro decks build wide board quickly to burst you down. Slower combo decks don’t rely on playing minions to win.
Control/Combo warlock isn’t interested in random discards.
If zoo makes it back somehow, it could work … maybe.
I wonder if Discard is coming back this year in some form or other. The team might be setting up Discard Lock for this year.
