how do double faced cards work mtg Uhhmmm does this sided card work? how do double sided cards

Looking back at past Standards, some have had a lower average price thanks to one really cheap deck that is essentially an outlier (a good example of this is the $85 Mono-Red deck back in 2015 Standard, which helped hide some really expensive decks in the same format and make the format look cheaper than it actually was)

Revolving around her first effect of reducing Rare and Mythic Rare spells by 1, we have only 17 cards in this deck that do not work with that mechanic, and of those 17, 9 of them are 1 cost or 0 cost, so it's really more like 8 cards that don't really synergize

If they see play across multiple formats, even more so

But one thing unifies every single one: changelings

Dominaria Remastered was perfect to saturate an otherwise thin market, and bring Yawg down to what he is now: around $15
