I am sure that I am not the first person to think of this combo but I couldn't find it anywhere in the horrible ffg forum search so I'm posting it again. I know that the Carrion Bird has been errata'd to only be able to affect PRINTED raven cards, however I could not find any such errata for the Black/White Raven attachments. So with that in mind, is there any reason that I cannot use the Copper Link to give my Tin link the raven trait to circumvent the Black/White Raven's immunity, then, using the newly raven -ized Tin Link, discard the Black/White Raven from play?
Card text below for reference.
White Raven
Raven, Creature Immune to non-raven cards. Attach White Raven to your House card and discard all other Raven attachments from play. It is Winter. Each player takes 1 less gold token when he or she counts income.
Black Raven
Raven, Creature Immune to non-raven cards. Attach Black Raven to your House card and discard all other Raven attachments from play. It is Summer. Each player takes 1 additional gold token when he or she counts income.
Tin Link - Response: After attached character kneels, choose and discard 1 non-chain attachment from play.
Copper Link - Response: After attached character kneels, choose 1 card in play. Until the end of the phase, that card gains a trait of your choice.
