The most expensive cards in a format also tend to be expensive because they see play in multiple top decks
While it might be tempting to have a high curve, its going to be better to use those treasures to play more Dragons and more synergy cards, because Izzet is a color pair that can feasibly draw through a lot of cards
This is the first time Wizards has done this for a Serialized card, which should set this version aside as extra-special
As a WPN wide distribution promo this version of Bolass Citadel has plenty of copies lingering in the secondary market, which is doing a great job of keeping its price in check
Starfield Vocalist A more open-ended Panharmonicon in creature form, I expect ETB/flicker decks will be interested in Starfield Vocalist even before they consider the cheap warp cost
Ill keep holding my copies, but Im not eager to buy any more
