Ghost Quarter I have the lovely distinction of being the designer of second highest amount of banned & restricted cards (and I'm slowly catching up to Richard)
The bounce strategy removing cards from play into your hand adds a significant level of difficulty to the Ruby/Amethyst deck compared to what this deck looked like way back in The First Chapter format
To combat this, many of them have some sort of downside Animate Dead gave the monster -1/0, Exhume allowed both players to reanimate a target in their graveyards, Stitch Together required payment of life but the downside was never really enough to deal with pulling things like Griselbrand, Elesh Norn, Grand Cenobite, Sun Titan, and the like out of a graveyard for free
So, except for some overpriced cardsthere, I said it, hate me collectorsprices wouldnt be affected that much because demand would increase with supply
