Coming in at number six, we have Sheltered by Ghosts
If Im playing a deck with more than a few of those types of cards in it, I always want to go no earlier than second
Then you can use this in decks with evasive dorks, combat triggers to give menace to, and Dimir Commanders like Vela the Night-Clad and the flying Dragonlord Silumgar
Where the team did push the creative envelope was in the naming convention
Here are the card counts and likelihood of getting each type of card, noting that this slot only has non-foil cards found in it: 8 Rares (18.18%) and 1 mythic rare (1.14%) with the showcase magnified treatment 4 Rares (4.55%) and 3 mythic rares (1.7%) with the Ravnica City treatment 13 Rares (29.54%) and 11 mythic rares (12.5%) with the showcase dossier treatment There are an additional 4 rares (4.55%) and 3 mythic rares (1.7%) with the showcase dossier treatment that appear half as often as other rares and mythic rares due to having other variant versions available
For example, the Alpha and Beta sets, 1993 and 1994, respectively, are highly sought after
