MArcomage

This is really expensive for a card whose virtues aren't really immediately obvious ("yay, I paid 25 resources to draw bronze golem"). Also, what if your opponent doesn't have any cards that meet the criteria?

it's not a card for hidden games and I agree expensive

Even if you're not playing a hidden game, double-keyword commons are quite common, and your opponent can easily foil you by just keeping at least one in his hand.

I would ditch that prereq, and for that price Id say it's allowed to exclude commons as a target.

On a side note:
The effect is more of a thingy my Illusion deck would use.
