... Why does this card say "unrezzed"?
Now for the more complete examination because of the 200 character minimum:
Three credits is expensive, and it doesn't let you swap rezzed ice, making it largely useless, as excluding derez effects, Reshape swaps one unknown layer of defence, that you presumably have yet to let the corp rez, for another unknown piece of ice, that you have no reason to think is going to be any cheaper to break; let alone be enough cheaper that you are going to get the money back for playing this card, let alone including it in your deck.
This probably worked on all ice in early testing, but either was misprinted, or was nerfed and didn't get tested properly after the nerf.
