The idea of a v-card is not to bring out an errata but to create a new card. If we would V FTTWC, uyou could play 1 V and 3 non-V, or any mix possible (and legal). Its not that if we V a card the non V cannot be used anymore. So a gametext adding: when not in FOTR block, do this wont work... Also too much text on a card is never good. Text should be short and clear.
