So, as prompted I'm looking at this compared to my goblin deck. I think as it stands I would have to get a serious edge before your turn 3 or lose entirely. What I'd recommend you sideboard are some weenie creature killers for just that reason.

Have a look at my Blue/Black Control deck for what I mean. Suffocate and Disfigure are awesome for getting rid of stuff like Warren Instigator which can be a real jerk.

Oh... I get it, your duel lands seem to count as both in many cases, understood.

I'm not seeing why you only have 1 of each basic land in the deck when so many critters you have seem to benefit from you having those basic land out. Maybe if you had something like Rampant Growth or Harrow, or hell both. That would make sense.

A lot of different cards instead of standard playsets in primary cards. That makes it hard to look at, and likely very unpredictable in play. Sorry but I can't say much more than that on a glance.

Consider enchantments, sorceries and instants that play to your entire side (not targeting a creature) but will benefit your creatures. Beastmaster Ascension and Overrun for example (both green), probably plenty of similar abilities, but those are just off the top of my head. Those spells could easily put these already beefy creatures over the top.

I would say Ponder and Archmage Ascension are your friend here too mate, ponder of Mysteries any day, it's so much cheaper and more powerful in a lot of ways. Archmage Ascension kind of conflicts with Lorescale Coatl but it's simple enough to only use it to fetch cards that you want, like Lorescale Coatl...

Looks like combat damage, I'd say. Gather specimens is kind of neat, expensive though.

I also use Soul's Fire to get goblins out with Warren Instigator if my opponent has threatening blockers. It works great with the Goblin Chieftain or Siege-Gang Commander. You end up paying their cost or less and putting them into play and dealing at least 1 damage to the target player, more if you already have a Chieftain out.

I love standard goblins. I personally put in Voracious Dragons and left out the Roughriders. Shortcutters are probably useful, but as a sideboard maybe. Quest for the Goblni Lord is good, but potentially by the time it's useful it may be disenchanted or the game might even be over. Now if you look at Quest for Pureflame that can charge up in a single round with four goblins attacking and left unblocked. Then on the following round you can pop it.

I think Archmage Ascension would also serve you well especially if you got at least one more draw card like Ponder in there. I really like this general concept of a deck anyway, but you might perform really well if you could get all the burn you wanted out, whenever you wanted it and deal double damage each time. I may now be inspired.

I would totally run this Duel Blue/White and skip all the green. Use artifacts to get your mana, and even to get extra land played. Consider Archmages Ascension as well as a card drawing engine. Everything in the deck other than Pestermites, Adarkar Valyrie and Blasting Station should be all about getting to those 3 cards, and having the mana to play them. This is a great extended deck, +1

Neat, I was going for a standard deck myself so I didn't have the same options. One reason I really like Walking Atlas over say Skyshroud Ranger is that its ability can play on your opponents turn. Which isn't such a big deal in this deck as it can be with other landfall decks. I'm considering adding Adventuring Gear as well though, since it would help preserve some of the flimsier critters.

I like some of what you've done here, check out my most recent goblin deck.

Some of the goblins you have are just bad IMO. The Pikers I can definitely live without. Seriously consider Goblin Guides as a replacement, their ability has about a 1/3 chance of benefiting most decks you use it against each time they attack, but they are amazing first turn blockers as well. I'd also do away with the Raging Goblins, your Warren Instigator/Basilisk Collar combo aught to make sure you get plenty of goblins on the table cheap, try some Seige-Gang Commanders to work synergy with that.

I also think your dragons play a bit too slowly, I personally use Voracious Dragon.

I have to say Basilisk Collar is something I aught to think about sticking into my deck with Warren Instigator it makes him a REAL pain to block. If there were an easy red source for trample on him too it would be pure win. That being said Soul's Fire is another nice way to get expensive goblins into play cheaply, or finish someone off with a beefed up Voracious Dragon.

I've been hearing Unstable Footing is hard to make use of in Standard these days, consider swapping it for Lightning Bolt and sideboarding it or something that's what I did basically.

Don't underestimate Quest for Pure Flame either... double damage for an entire turn is sweet.

Giving you +1 for the collar idea.

Holy $50/copy mythic rare sideboard batman!

Actually elements705 has a point... but because I like to argue with anyone who would bother to make such a point against an obviously good idea. +1

I'm a magic re-noob. I'm learning all over again, since last time I really played was 6th.

No longer standard, suggest updating deck or name.

Gempalm Incinerator is always better than mob justice in a goblin deck. It's cycle ability will net the same result, or play it and have another goblin.

Check out my deck "Goblin Powered Burn" for an example of a very creature heavy goblin deck with only Goblin War Strike for direct burn. The deck also uses an artifact based combo, and a creature based combo to deal direct damage. http://www.mtgvault.com/ViewDeck.aspx?DeckID=42532 is the link.

Quash does it too.
