DESCRIPTION [Before Conspicuous Snoop was printed]
This deck, in my personal experience, is probably the best way to performe with Goblins in Modern. Sure, classic legacy-style Ringleader-Goblin is appealing, but it has not all feature to overperform in the format. Goblins sometimes need a way to win as fast they can because of so many combo/non-interactive deck and later than turn4 is almost a loss, specially in game1. Beyond that, as every creature-deck is weak to a ton of removal spells.
This deck overcome these issues: it is a classic Goblin aggro-midrange that wins both by attacking or going off (just like the old Splinter Twin..) and it is also resilient to removal-decks thanks to new techs like Persist and Unearth (that can be also a piece of combo).
