Renfri is unironically lore appropriate for what she is doing to the current Meta. I have a possible solution.

I have a potential lore friendly solution to the Renfri meta right now so indulge a little lore for those who are unedumacated on Witcher history from the books.

Renfri was prophesied to be 1/60 cursed girls born under The Black Sun to bring about the destruction of the world and unironically, anyone having Renfri in their deck this season is destroying the meta. Stregobor hired Geralt to kill "a monster", but Geralt not knowing Renfri was a human princess had a code not to kill monsters who did not endanger people regardless of prophecy.

Although Geralt eventually killed Renfri, he would rather have not done so initially as Stregobor suggested would be the "lesser evil". Geralt did not accept initially because he didn't want to have chosen a lesser evil over a greater evil by killing Renfri before she eventually killed someone herself. Innocent until proven guilty was Geralts code here.

Wouldn't it be lore appropriate to balance her card by adding or revising a Geralt card to summon her to the board like Irraquax but you have to play the Blessings/curses immediately. It would be the "lesser evil" just like in the books.

The Stregobor card could then be revised to have his ability changed to where any ability you choose when playing Renfri is casted back on the deck who played her and not on the opponent. Renfri then destroys herself in the process. This is the "greater evil."

Probably too much for CDPR to consider, but it would be badass for us book nerds who love some Gwent!
