The Cheese Stands Alone – Unglued rare. Eighth Edition contained a never-before-reprinted card from every set in Magic. The plan at one point was to bring The Cheese Stands Alone into "real" Magic, but the rules regarding silver-bordered cards made it impractical. The mechanic finally made it into Future Sight, though, in the form of Barren Glory.
Offering to Asha – Alara Reborn common. Offering to Asha is an exceedingly balanced card. The converted mana cost is four, the mana mentioned in the rules text is , the spell gains the controller 4 life, and the flavor text is four lines.
Rise & Fall – Dissension uncommon. If you look carefully at the left side of the art for the "Fall" side of Rise & Fall, you can see the Rakdos symbol carved into the wall of the pit!
Tarpan – Ice Age common. A tarpan is a kind of wild horse, which has been extinct since the last one died in captivity in 1909 in Russia. So if you've been trying to summon one and have been having trouble for the last hundred years, that's why.
Scryb Sprites – Limited Edition Alpha common. For something clearly out of the color pie (a common flier for green? For one mana?), Scryb Sprites stuck around for a surprisingly long time, appearing in every core set through Fifth Edition.
Cheatyface – Unhinged uncommon. Cheatyface essentially introduced a new minigame into silver-bordered Magic, in which players of a certain mindset strove to come up with new and more devious ways of getting it into play. Randy Buehler, for example, once used his baby as a shield while getting it into play. That's a lot of work for a 2/2 flier!
Soraya the Falconer – Homelands rare. Soraya the Falconer got better with the Grand Creature Type Update; now, even owls, albatrosses, and rukhs can get benefit from Soraya. This suggests that Soraya is an excellent falconer, as opposed to that Sunastian Falconer, who doesn't actually interact with the beasts of the air at all.
Belfry Spirit – Guildpact uncommon. Belfry Spirit implies one of two things. Either bats naturally hang out with ghosts (which sounds logical) or there are, in fact, bats in almost every belfry.
Chicken Egg – Unglued uncommon. Chicken Egg is, of course, a reference to the classic Rukh Egg from Arabian Nights. Sure, it's randomly instigated instead of happening when the egg goes to the graveyard and a Chicken instead of a Rukh, but Christopher Rush's egg is clearly the same one he drew the first time.
Rogue Elephant – Weatherlight common. Rogue Elephant comes with a pretty harsh drawback for a one-mana 3/3. But it was printed in the same set as Harvest Wurm, which could help counteract that drawback at two mana. Add in Fallow Wurm, and you can see how lands were going in and out of the graveyard a lot during Weatherlight.
Form of the Dragon – From the Vault: Dragons rare. On the From the Vault: Dragons printing of Form of the Dragon, Sarkhan Vol can be seen turning into a dragon. If you want to see this presented as a piece of sequential art, stay tuned for part two of Awakenings, which will arrive on Thursday.
Mercadian Atlas – Mercadian Masques rare. Mercadian Atlas doesn't want you to play a land. But if you also had Walking Atlas, you could get around that by putting the land directly onto the battlefield. Atlases have synergy!
Chronozoa – Planar Chaos rare. Does it seem strange that Chronozoa has Vanishing? After all, its ability ensures that when it runs out of counters, it doesn't really "vanish" so much as "double itself."
Chisei, Heart of Oceans – Betrayers of Kamigawa rare. Chisei represents the essence of intelligence, and its very presence heightens the intellect of other beings. That was pretty much all the direction artist Matt Cavotta was given, since the spirits of Kamigawa were notoriously strange and abstract.
Hyperion Blacksmith – Legends uncommon. Although we now call Hyperion Blacksmith an uncommon, it was officially a "U1", meaning that it appeared once on the uncommon sheet. The five Legends rarities were C1, C2, U1, U2, and R1.
