But I think the best stained glass card is this Secret Lair Arcades Sabboth by Eshpur
It pairs well with other cards that want you to send artifacts to your graveyard, like Marionette Master and Myr Retriever, and the ample self-mill found in these colors like Grisly Salvage
Sadly, the older codes from these decks have now expired, and the decks themselves are very difficult to come by (they're all unavailable on Amazon US and UK) - so you'll struggle to find an unopened copy with an intact code for a reasonable price
Depending on your set and collection size, you might need more sorters
Bounce somewhat scales well with more bounce and so Riftwing's bounce aspect is that much more potent when you have more of a bounce theme going on
That being said, even with fraudulent bids being steadily removed, the card appears to be receiving a flow of genuine bids interested in acquiring it for well over $300,000 already, and it wouldn't be that surprising to see the price actually hit the $1,000,000 mark before the auction ends
