Infernal Spawn of Evil – Unglued rare. The staff of Daily MTG is taking two weeks off to recharge their batteries. While we rerun our favorite articles from 2009, we encourage you to wrap yourself in a scarf, have some hot chocolate, and tell yourself "It's coming ... back on January 4, 2010."
Goblin Bookie – Unglued common. Like many Un-cards, Goblin Bookie doesn't work perfectly within the rules. It turns out you can't activate an ability in the middle of another ability resolving. To do something like this in regular Magic, you want something like, say, Krark's Thumb.
Mons's Goblin Raiders – Limited Edition Alpha common. Here's something to consider. Mons's Goblin Raiders is plural, which means that it takes more than one of them to make up a 1/1. Or there's the generic Goblin Raider, which is a 2/2 all by itself. It turns out that Mons's personal goblins are actually weaker than the regular kind!
Stream Hopper – Eventide common. The phrase "better half" usually refers to one's spouse. In the flavor text for Stream Hopper, however, it appears to have been used literally. Just what made the missing left arm and leg better is left unexplained.
Squee, Goblin Nabob – Tenth Edition rare. Squee is many things: a member of the Weatherlight crew, a Vanguard card, comic relief, a combo enabler, a nabob ... the list goes on and on. But he rarely gets credit for being responsible for one of the great Stealth Puns in Magic history: the squeeze toy called Squee's Toy.
Arms Dealer – Mercadian Masques uncommon. In Mercadian Masques, we saw a different kind of Magic goblin: smart and cunning, as opposed to dumb and wacky. But as Kyren Glider points out, they had their own flaw. Instead of the usual insane recklessness, Mercadian goblins tended toward the cowardly.
Statecraft – Mercadian Masques rare. Instead of representing a magical fog that keeps armies from finding each other, Statecraft depicts the vizier of the Saprazzans physically separating a Mercadian and a Sprazzan. When things get rough, the vizier calls in Saprazzan Bailiff.
Crime/Punishment – Dissension rare. Not only is Crime/Punishment a split card, it's actually split between guilds. The "Crime" side shows an Orzhov thrull digging in a cemetery, while the "Punishment" side has a Golgari shaman bringing forth a horde of bugs.
Counsel of the Soratami – Tenth Edition common. After its first appearance in Champions of Kamigawa, Counsel of the Soratami had a brief run in the core set, showing up in both Ninth Edition and Tenth Edition. It was replaced by the less Kamigawa-specific Divination in Magic 2010.
Tromp the Domains – Time Spiral uncommon. The flavor text for Tromp the Domains references Benalia, Llanowar, Hurloon, and Urborg. Presumably, that makes the Domain count "four", with the missing basic land type being Islands.
