Don't trust your secrets to the sea.
I would recommend blanking a foil, either by using acetone to just take off the ink (blank shiny canvass) or peeling off the foil layer entirely (blank white canvass, my preference). Using thin sharpie markers you can then write on the text and approximate the art. I think this gives the clearest presentation, and even if you aren't amazing at art, the older iconic stuff you will be copying has simpler images that are so well known that even a passing resemblance should allow an opponent to clearly identify the card.
@kingleovold Hitting shop itself is equivalent to hitting shop and sphere. I don't know how many taxing effects the deck can tolerate with only 1 workshop. Ravager is so heavily creature based that you could probably still run 4 thorns, but ancient tomb damage stacks up quick. White eldrazi may wind up being the better deck at that point
@chronatog Berserk and Show and Tell are not on the reserved list.
And while it is true that wizards doesnt manage the secondary market and are not generally responsible for the prices there, they could be liable for losses incurred through reprinting, because of the promise that they made.
