This is the Thijs High Legend Discard Zoo Warlock Deck he built and was playing on stream. A lot of discardlock lists dropped Darkshire Councilman, but I think this card necessary in this build. Sometimes you need that large threat with a decent health total to survive some of the board clears like Lightning Storm, Holy Nova, etc.
This is probably the most relevant and strongest discard warlock list right now, so run with this list if you want to play some discardlock.
