Goblin deck

Goblins are a pretty well-tested tribal build. I'd say that you need to have as many lords as possible that are legal in your format (Goblin Chieftain, Goblin King) as well as 4x of both Goblin Bushwhacker and Reckless Bushwhacker for when you vomit out tokens, so they've all got haste and are ready to go. Krenko, Mob Boss is fantastic. You may also need some draw, since goblins are cheap and you'll find yourself top-decking pretty quickly, so I included Warlord's Fury and Risk Factor into my decks.

Battle Squadron, Chancellor of the Gorge, and Goblin Snowman are neat, but there are much more efficient ways to run Goblin decks. You really want to decide whether you want to go wide with a ton of tokens, or build up your field with lords and fling/goblin grenade your opponent. I'd say that Goblin tribal is a strong, well-sorted tribal deck that, unless newer sets build up it's support, has been pretty much optimized in Modern.

But if you want to build something janky for kitchen table, the world is your oyster ;)

Also, I noticed you've got 66 cards in your deck. Assuming that isn't because you're still tinkering, you need to drop it down to 60. Efficiency is key, especially when you're counting on specific cards to come up at specific times, and the more cards you have in your deck, the less efficient it becomes. Many others have said it much more elloquently than I can, but it's a good rule to live by.

furnace of rath is pretty hard to play if you can't defend, because you also take double damage! If you intend to play 4x of them, I'd consider playing 4x goblin grenade.
