One of the main goals of this deck is getting the "Sniper Combo" on the board. This should be your number one priority going into a game against MOST decks. It allows for almost complete control over the creatures in the battlefield, with the added bonus of a 4/4 Flyer. The combo consists of two cards.
This combo works by using Goblin Sharpshooter's third ability to tap to deal one damage to a target creature. This then triggers Horobi, Death's Wail's ability, which destroys that targeted creature. And when that creature is destroyed, it triggers Goblin Sharpshooter's second ability that untaps him. This allows you to repeat this process until you clear your opponents board of creatures. (This ability can also be played on your opponent's turn, allowing for instantaneous removal of all your opponents creatures.)
There are two playsets of each card in this deck to maximize the chances of you drawing them. There is also a playset of Goblin Matron, which allows you to tutor for your Goblin Sharpshooter AND has great synergy for the second half of this deck, "The Goblin Army."
