Looks like their solution is to use Oracle to retcon the names of the cards
Won’t that mean that players who own The Walking Dead cards can now play both versions in their deck?
No, it does not. The cards, in Oracle, would identify that they represent the same card and would be treated by deck building rules as if they were the same. Think of them as functioning identically to the Godzilla skins..
I think the decks that could make use of different duals would be the non blue agro decks like various hate bears / humans. So if there was enough duals that are good enough those decks could drop fetches and even possible incorporate more anti fetch measures.
