Messenger already pretty much has this effect with it's added gain effect.
On another note, I understand why they cut Woodcutter, Chancellor, Spy, Secret chamber, Scout, Saboteur, Thief, and maybe even Tribute. But I don't understand why did they cut Feast, Adventurer, Great hall, and Coppersmith? Bureaucrat, Wishing Well, and maybe Duke seem like much more "cutable" cards. Is there a post somewhere about there reasoning? Nvm I found it.
