Green has a lot of potential in Aetherdrift
Im not 100% sure about the role of Sliver Queen in the list, but beyond being an iconic and extremely fun card to include, it likely serves as a win condition in control mirrors, where both players tend to trim down on removal and games often go long
*Update* The digital ground appears to be discontinued so use the InkAid, its the same stuff
However, misprints that make the card confusinglike a Forest with Plains art, a half-and-half miscut that shows two cards, or anything blankoften arent allowed because they can mislead opponents or reveal information
There are lots of cards that generate card draw with dying creatures but not so many that give you mana
If a card cast this way would be put into a graveyard this turn, exile it instead
