Just opened him as a golden on my phone, should I dust it? He looks like a win moar card with the 4 minion requirement.

I've seen him used in paladin and zoo when TGT came out, but not any more. I'd dust.

If you need dust then y if not,keep it ,its golden leg and could be more viable in future.

He's actually a staple card in new zoo zoolock..
At least in the hobgoblin/tinyfin/wisp deck.. maybe not in more traditional lists.
Still with cards like implosions/gangboss its a reasonable card.
