Those were all Bands of Misfits. Now Throne Room 9 of the real Coppersmiths to give you 69.
Throne room your king's court
First KC play, play Procession -> Coppersmith, Coppersmith, GR (save the coppersmiths)
Second KC play, Play BoM(as Procession) -> Coppersmith, Coppersmith, Rouge (save the coppersmiths, TD with WT)
That's +8, and all the Coppersmiths are still in your hand. You can do this 10 times, for +80, then play all your Coppersmiths (as none of them finish in the trash) on their own for +90.
Can optimize a little. The last few passes you could Procession another coppersmith, as otherwise you'd only be able to play it once. Should probably be able to get to +93 or +94.
Now I'm interested to see what the maximum is...
