Uncounterable Goblins for the win. The Mesas are more there just for the little bit of deck thinning, but you replace those with 4 Mountains and you're golden, for a lot cheaper too.

At 3 CMC, he is about the high end average for Goblins. All of my Goblin decks have always run a goblin "Lord" (i.e. Goblin Chieftain), and those are always 3 CMC. For giving all of your creatures haste, as well as sitting on a solid 2/2 body, he's a decently well rounded Goblin. And honestly, you're complaining about a 3 CMC Goblin when you already have Guttersnipe, who is also a 3 CMC goblin, and Krenko, who is a whole 4 CMC. If you ask me, without Haste, Kreno is way too expensive for a Goblin. But, with Hellraiser Goblin in play, you can drop a Krenko, and tap him for Goblin Tokens, and swing with all of those Goblin Tokens all in the same turn!

Hellraiser is definitely worth considering for standard Goblins. Also, Banners Raised may be a good alternative for Dynacharge if you're looking for Battle Cry type effects. Banners Raised is only 1 mana, and gives +1/+0 to all of your creatures. That means that for just 1 Mana, you can probably pump out more damage than a non-overloaded Dynacharge. And other than the fact that it costs you two cards, a pair of Banners Raised will end up being better than Dynacharge in the long-run.

Also: Harrow.

Never really thought about using Spirit Guide. Definitely a strong idea, but it does take away some extra offensive power for a goblin deck like this. I thought about Siege Gang Commander, but without the Instigators, he's a dead draw in a deck like this. If I hit 5 mana, I'm usually going to be quite bummed. Playing with Siege Gang is too reliant on other cards, I feel. And my other reason for playing Mogg War Marshal over Krenko's command is sort of a silly, but, I feel, solid one. The War Marshal actually gives me 3 bodies to use. War Marshal is a wonderful chump blocker, if they have something attacking in to me. Throw my War Marshal in front of it, only to be replaced by another Goblin.

Squadron Hawk says Hi. For a card that was once a staple in Standard, it has to have some merits for sure. It gives you card advantage on your opponent, makes sure that you hit creature drops, and is a solid critter. Plus, you guessed it, it's a bird to boot!

I'll gladly step in on this as well. I definitely have a fond love of Goblin decks, and in the same frame of thought that this is quite far from the true frame of how a goblin deck should function. I know that some people aren't able to build ideal decks, but with something like Goblins, even ideal isn't always necessary. I'd be more than glad to add some input into helping you build this to be a stronger deck.

As a side note, I just added a Goblin deck of my own that you can take a look at here: http://www.mtgvault.com/lepellier/decks/modern-goblins/

That deck is looking a little more towards an optimized Goblin deck build, and maybe it can also help spring forth some ideas.

Apparently you aren't reading what I have written in the "Deck Description" section.

Cavern of Souls is a dang good land for any tribal deck. Especially in formats such as Modern or Legacy. Being able to cast creatures without the fear of them being countered is pretty legit if you ask me. And especially with goblins. Goblins that can't be countered means that they usually have to have some sort of instant speed removal to even think about dealing with Goblins.

I have a personal vendetta against Syncopate, I guess. For some reason, I just really dislike it as a counter spell. I'd much prefer Dissipate or, in this case, Negate. To me, they just seem more aggro oriented, and are more of what I'd be looking for. The Bonds of Faith just have so much flexibility in a deck like this, because they are buffs spells for your creatures, and will generally be a Pacifism for your opponents. Fencing Ace also just gives that extra little bit of power to the enchantments since he has a built-in Double Strike.

I'm a real stickler when it comes to using double mana costs like the Paladin in a multi-color deck like this, but in all honesty, the Paladin would be strictly better than the Stealer of Secrets as your 3-drop creature. Then you'd just need to swap out an Island for an additional Plains probably.

I already have Ghostform in the deck. I haven't looked into Gatecrash quite yet for this deck, but I have looked at the spoilers. Rancor is OK, but this deck doesn't need trample. It's more about just hitting with unblockable Hexproofed creatures.

Somehow I completely missed that my deck is full of Humans...I don't know how I missed that. Well, Champion it is!

If I were to cut a creature, it would probably be the visionary over the Augur. Augur is just that much better when dealing with a deck the uses Instants and Sorceries like this one does. My biggest problem is then finding another spell to replace the visionary with.

That's why I have the Selesnya Charms. But I have been thinking about Rancor in there anyway.

Tricks of the Trade is a decent option, but personally, I do prefer Spectral flight for a few reasons. Spectral Flight is cheaper, and on the creature that I most want to use it on, it's not redundant. It also allows me to BLOCK fliers if I need to, which is something that I always seem to run in to issues with. I mean, sure, having the unblockable ability is a wonderful thing, but at the cost of an additional mana, it's kind of a waste, I find. I do feel like I need to rearrange some of my creatures in the deck. The Pilgrim and Wingcrafter seem to be probably just a little bit underwhelming, and stealer of Secrets may not be quite what I need to be looking at for a creature.

Rootborn Defense and Safe Passage only work well against certain types of sweepers. A counter spell, such a Negate, will cover all of my bases when it comes to board wipers. I actually have another deck very similar to what you were thinking about building that uses Traft. I just like to think of this as a working Budget version.

Detention Sphere is a little more than I want to run, but I have been highly debating on getting a few at some point. I do have the O-rings in the sideboard, mainly to replace the Bonds of Faith if I feel that they are beginning to become less useful. My biggest worry in the entirety of Standard are Board Wipes, like Supreme Verdict, so I'm trying to keep a mindful conscious of that in putting together my Sideboard.

Same reason that there's no longer any Thragtusks in here. Too expensive (Price wise).

Raise The Alarm is a great card for token decks, however, it is also rather out of standard.
