The first one that comes to mind is, of course, Cori-Steel Cutter
Its mostly due to how you choose to sort your cards rather than the storage method, so Ill go into this a bit more later
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
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
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
