The beauty of this deck is that Goblin Recruiter sets up your deck meaning you can get any 5 goblins that you want. Add on the fact that Lightning Crafter and Changeling Berserker plus any sac engine like Skirk Prospector, Goblin Chirurgeon, Mogg Sledder means you can get any 15 goblins you want from the top of your deck.
Goblin Recruiter won't always resolve. In fact, given how it (almost always) immediately win you the game, chances are it won't resolve too often so our deck needs a way to play without him. The deck runs plenty of ETB trigger goblins so cards like Panharmonicon, Molten Echoes, Flameshadow Conjuring, Blade of Selves, Strionic Resonator, and Kindred Charge make the deck pack one hell of a charge. By nature of being a goblin deck, our enemies also need to be scared of our potential to deal serious damage. Impact Tremors, Goblin Bombardment, and Shared Animosity make our creatures scary when they enter the field, when the attack, and when they're about to die.
The deck also falls weak to board wipes and removal of important creatures. Goblin Chirurgeon is a perfect sac outlet that also saves half of the board in the event of a board wipe. Eldrazi Monument makes our creatures much scarier, doubling their attack in most cases, giving them evasion, and making them indestructible. Sacing a creature a turn isn't a big deal, we're goblins, we're gonna be doing that anyway.
What about removal? What if our enemy pleases an artifact or creature we just need to get rid of? As a goblin deck your general answer is going to be "Someone else can deal with it" or "I don't care, I'm going to kill you first". That said, this is a much slower goblin deck than playing something like Krenko, so we need to play our removal carefully. Goblin Cratermaker deals with artifacts and eldrazi. Goblin Assassin forces enemies to sacrifice a bunch of their creatures. Goblin Sharpshooter along with a sac outlet have the potential to destroy plenty of creatures. Goblin Trashmaster sacs goblins to get rid of pesty sol rings and other artifacts. Stingscourger bounces creatures. Last, but not least Goblin Grenade is one of the most efficient spells any goblin deck could ask for.
The deck wants to get Muxus out asap, so it runs quite a bit of ramp too. In terms of goblins we have Skirk Prospector, Treasure Nabber, Goblin Warchief, and Cheering Fanatic help us in that regard. We also run Brightstone Ritual, Sol Ring, Hedron Archive, Worn Powderstone, Ruby Medallion, and Fire Diamond.
