MArcomage

I find this card very amusing and one of a few highlights for a non-keyword deck now that new and new keywords are introduced.

What I would like is a slightly higher chance to get it. I would suggest either raising its cost and making it persistent, or have a support card to summon it (maybe a high cost common card with the same mechanic as magic lamp)

other option would be to summon non keyword rare or non keyword attack rare

I would also add the suggestion; make it so your opponent (and probably you too) can't draw rares from the effect, since currently the Witcher's monster-slaying can actually put more monsters in your opponents hand than they had before.

If you felt the need to make it overpowered, you could also prevent drawing of uncommons.
