Discard still isn't all that great, but it's probably the most fun deck out now (to me, at least). And just look at that glorious hand I got from Deathwing. I spent all my dust and crafted Jeklik and don't regret it at all.
(And to top it all of Storm Bringer turned his minion into the vanilla 1/2 Druid legendary)
Would be a lot more interesting if you could choose which one goes to your opponent. Missed opportunity, now it's sadface when you get this card from packs.
even if you could pick it'd still be pretty bad
hell, even if it was just discover a card for yourself and not your opponent, it still wouldn't be played. the only niche could be if you're tryna fill you opponent's hand to burn cards from their deck
