Did Image of Jealousy really matter that much? From personal experience, I haven't liked it. Decks that rely on TGT often have a way to get rid of it, and it seems like the only times it has every stopped my opponent from rescuing has been when I got to put it on TGT early in the game. It seems a card like Writ would be better in place of it, beings it seems pretty useless if your opponent isn't playing TGT (okay. It can stop a pesty TSA or something, but it can't do much fort wise. What forts are commonly played? Z's Temple? Obadiah's Caves? Those aren't going to cause your def too much trouble anyway)
EDIT: I just read my message and realized I used the word 'seems' to much. I started to edit it but decided I'm too tired
