But their trap Patronus deals with banish right?
And it's continuos. So you keep spending resources to banish but they keep getting her back to the deck for the cost of adding 1 spell to their deck. Feels sooo balanced.
Someone posted an answer on it already but you can use the effect of Blue Eyes Solid Dragon to permanently negate Verre. Then don't destroy her. Just negate the others and deck them out.
I did it once.
My Solid Dragon negated 1 Fortune Lady Every + 2 Verres. He had 1 card in his deck.
I so much wanted my opponent to deck out that I forgot to use Enemy controller to win the game several turns earlier. Then I lost. But it was still memorable.
