Many of these cards aren't really weapons. They're just forced into that slot. Hell, some them can't even attack.Weps are hard to read cause they aren't like the old school weps that just do damage. That's cause Blizzard's setup of allowing weps to go face means they have a hard time balancing so they have to get creative.
All of this feels so damn pointless with weapon removal being so insane. I think they should have introduced an "artifact" slot or something by now but I guess it's way too complicated for HS players, just like deck slots.
This druid card actually makes sense as a weapon though. And playing against it isn't as simple as drawing your Ooze or Harrison and slamming it down asap. That's really good.
