Guttersnipe Adding a spells matter theme to your Goblin deck can pay huge dividends depending on who your commander is, and this unassuming little outcast boy or girl in the streets of a city (which is the definition of the word guttersnipe) is one of the main reasons why
Grievous Wound also helps accelerate your opponents loss of life by halving their life total each time they take damage
The sac of three for one is worse, card wise, but if you get a game ender like Blightsteel Colossus or card draw machine like The One Ring, that'd be worth it
It can generate mana, and if you're not using it for mana, can tap it to draw a card instead
If going wide doesnt sound like your style, you can always attach Light of Promise to Daxos himself and try to win through commander damage
Not only that, but decks are incredibly expensive
