I also played around with the idea of forming a deck around "Drogskol Captain", the main disadvantage is, that it is to slow against common modern or standard decks. But perhaps some of my Ideas will help you:
As cheap spirits I used "Spectral Rider"(Intimidate), "Kaijin of the Vanishing Touch"(Bounces blocked creatures back on hand) or "Lantern Kami"(Cheap and flying). The rider is also a great creature to carry "Inquisitor's Flail" to your enemy. "Rushing-Tide Zubera" is a good blocker and a nice choice for carddraw.
As support I used the following instants/ sorcerys/ equipments: "Skillful Lunge"(Buff), "Inquisitor's Flail"(Damage), "Spell Pierce"(Counterspell), "Mana Tithe"(Counterspell) and "Otherworldly Journey"(Protection and buff).

Ultimately I splashed green to get access to some other spirits, but that is not really a good choice for a budget deck

Our local dealer wants 2€ for one Wall of Denial, on other platforms it ranges from 0,15€ to 0,5€ ;)

"Legacy decks may consist of cards from all Magic card sets, any edition of the core set, and all special sets, supplements, and promotional printings released by Wizards of the Coast."

My Goblin deck locks like this:
http://www.mtgvault.com/muktol/decks/r-tribal-goblins/
I would change "Boggart Ram-Gang" to "Goblin Wardriver" and "Shrine of Burning Rage" to Quest for the Goblin Lord"

I would change from "Guard Gomazoa" to "Wall of Denial". The jellyfish can be pretty easily killed by a bolt, the wall should hold out longer. Backdraw of the wall is, that it's mana costs are more complicated
I would also up the number of "Perimeter Captain" and "Doorkeeper" to 4, as they are your main tactic to win.
"Curse of the Bloody Tome" is normally to slow with it's milling, i don't know i it works well in this deck. If you want to handicap your enemy, try "Chronic Flooding"
Also good walls/defenders are "Wall of Omens" (Carddraw), "Wall of Tanglecord" (Strong & possible reach) and "Steel Wall" (Cheap)

Keep her in the deck and try it out, that's the best way to see if there are cards that you don't like or never are able to play.
Let's do a little calculation: Chandra costs cc6, so I would say that you can play her in T8+.
You can activate her +1 or -2 ability once for sure, your enemy can't do something against that (As long as he wont counter the Chandra spell). So yo get to discard the enemys hand and draw 3 cards or 4dmg for 6 mana for sure.
Planeswalkers are the best targets to attack that there are in the whole game, so your enemy will do what he can to kill your Chandra. Normally you don't have enough creatures and simply don't want to waste your spell on enemy creatures, so She will have gone the next turn.
What did she then ultimately do? Discard the enemys hand and draw 3 cards or 4dmg on your enemy, and bought you a turn. Not really good for a cc6 which is normally supposed to win the game.

What I would do:
- 4 Boggart Ram-Gang: The 'Wither' ability is of no great use here
- 2-4 Mountains: I'm normally trying to build decks with a manabase of 20 lands, but when the most cards won't cost more than cc2 I would try it with 18 Lands. They can still be increased if it wont work.
- 1 Krenko, Mob Boss: Down to 3, you'll never want to have 2 of him in you hand

3-4 Infiltration Lens: For Carddraw
+ 1 Goblin Chieftain: Up to 4, yo will need him
4 Goblin Wardriver: 2/2 and Warcry
4 Mogg War Marshal: Produces 2 tokens and works very well with "Quest for the Goblin Lord"
2 Siege-Gang Commander: Better than "Beetleback Chief". The mana costs are irrelevant here, as you never want to hardcast them
+ 1-2 Spikeshot Elder: His abbility is expensive but works well with everything that pushes power..."Quest for the Goblin Lord", "Goblin Chieftain" and "Goblin Wardriver"
4 Warren Instigator: Best goblin there is aside from "Goblin Lackey". Move all 4 from sideboard to mainboard
+ 4 Quest for the Goblin Lord: Pushes all creatures you control

I have no experience with "Riot Piker", but personally I don't like creatures that say 'Has to attack every turn'

You'll have to experiment a little to bring the deck down to 60 cards.

Thanks for the advise, I changed from "Living Hive" to "Khalni Hydra" :)

Ticklyfish do you allready have your U/W Mill in the database? I love white and I would really be interested in seeing how this works. :)

I have built a similar deck for one of my friends, and he is very successful.
Take a look at
http://www.mtgvault.com/muktol/decks/r-tribal-goblins/
and feel free to ask if you need some help.

Personally I wouldn't put cards more exoensive than cc3 into a burndeck, and even the cc3 have to be real matchwinners
"Cinder Pyromancer": My stomach says that it is to expensive and does to little, but i have to admit that i have little expirience with this card
"Furnace of Rath": Costs to much to be of great use. You normally don't want to 'waste' that much mana in thing that effect the game only in the next turn. It's a great card for sure, but I think it would be better to cast 2-4 spells on your enemy this turn.
"Burst Lightning" and "Shock": It's damage/mana ratio is not good enough, as replacements I would take a look at "Magma Jet" and "Shard Volley". "Magma Jet" has also the advantage that you can Scry2 and thus see what your next 2 turn draws will be. If you want a cc1/2dmg spells "Forked Bolt" does a good job as it is flexible enough.
"Shock": Dito...it's damage/mana ratio is not good enough
"Skullcrack": I would put it into my sideboard, unless you have a great deal of lifegain decks as enemy's
"Chandra Ablaze" and "Chandra, the Firebrand": They bot cost to much. As replacement for "Skullcrack" and both Chandra's I would take a loot at 'burn' or RDW creatures like "Goblin Guide", "Vexing Devil", "Hellspark Elemental" or "Ball Lightning"

For my own Burndeck's sideboard I use "Vexing Shusher" against counter/control and "Wheel of Fate" when I really need the carddraw.

Hope I could help you!
(Sorry for my bad English, I am no native speaker :) )

depends on the decks you're up to. You have it in your Sideboard, if you feel that it is more usefull than e.g. "Dream Twist" just switch. With the upcomming rulechange it will be possible to have a Sideboard with less than 15 cards.

Depends on how stable your mana base is. If you can play with standard lands it's OK, otherwise you will need duallands.
The searchlands are good for searching standards and thinning out the lands. Also they help to activate the landdrop ability of your Hedron Crab.

-3 Nemesis of Reason
-4 Archive Trap (-> Sideboard)
-4 Twincast
-3 Terramorphic Expanse

+4 Jaces Phantasm (or Wight of Precinct Six, which looks better to you)
+3 Jace, Memory Adept
+4 Dream Twist
+3 Nephalia Drownyard

I didn't see a "Standard" Tag, and thus went for modern.

"Purely a mill deck" "Defensive" ?!? Something isn't right here...
If you realy want to mill your enemy to 'death' you need more possibilities to do so:

Instead "Wall of Frost" you could use "Hedron Crab". Put the Frostwall into your sideboard but I would look for a flying defender that I could use instead.
I would change "Nemesis of Reason" for "Consuming Aberration" and decrease it's number to 3. If you want to stay offensive think about 1 or 2 "Mirko Vosk, Mind Drinker"
Also I would put "Suffer the Past" into the sideboard. Its to specific to be usefull in every match. (OK, I don't know your game partners, but in our local modern tournaments I haven't had use for much GY hate)
"Jace Beleren" is a good choice for a cc3 slot, I would nevertheless change to "Jace, Memory Adept"

"Mind Grind" -> "Glimpse the Unthinkable". Its more efficient, and in combination with "Jace's Phantasm" you could have 5/5 with flying in Turn 2
"Traumatize" comes to late without ramp to be of much use. As cc5 spell it comes in turn 5 (if you manage to play a land every turn), at that point there should be allready be a great mass of cards in your opponents graveyard.
"Sleep" -> Sideboard. It helps you to buy time, but when you really mill your enemy to death he normaly shouldn't have that many creatures out.

With some space in your deck take a look at these mill-spells:
Duskmantle Guildmage
Breaking // Entering
Dream Twist
Thought Scour
Mind Funeral
Nephalia Drownyard
Millstone

Reduce the number of "Mentor of the Meek" to 3 or maybe even 2, you'll have to experiment with the number. You don't want to have him twice in your hand, because he is strong in mid and lategames.
I would remove also "Doomed Traveler" and "Fiend Hunter" for "Student of Warfare". Furthermore change from "Pazifism" to "Call to Serve"
If you want a powerfull removal, take a look at "Path to Exile"

A good Idea to get your creatures on the field could be the "Aether Vial"

As Sideboard choices in my Human Deck I use:
Lightning Greaves (Against point removal)
Ghostly Prison (Againat everything that hast more mass than my deck, e.g. Tokens)
Leyline of Sanctity (Against burn, mill, discard decks)
Proclamation of Rebirth (Against point and mass removal)

I would remove "Nemesis of Reason" for "Jace, Memory Adept". Jace has the advantage of not having to attack your enemy to mill. Furthermore I would put "Archive Trap" into the sideboard. You don't have anything that will force your enemy to search his library. If you're up against e.g. a green ramp deck deck, it's OK, but if your enemy won't have to search his library, it's a dead card.
Take a look at "Jace's Phantasm", "Wight of Precinct Six" or "Dimir Guildmage" for example. There is a nice (but late) combo you can make with Jace and the Guildmage.
"Millstone" and "Nephalia Drownyard" could bring more constant but mana intensive mill, "Dream Twist" would be another cheap millspell.

It looks a little bit chaotic.
Some unblockable creatures, some with undying, some without anything, combined with control-elements and buffs. You should first decide for one tactic, and then try to stay with it.
If you want to say with the unblockable's change the control for some more and efficient buffs like "Rancor" or "Vines of Vastwood". You want to be faster than your enemy, because if he sees that most of your creatures are simply bypassing his defenses he will bring out spot removal or try to be faster than you are.
If you want to stay with the control elements, its vice versa...remove the creatures that don't support your plan for something that helps you to keep your enemy where you want him.

I can only speak of my enemy's at the local game store. There I would encounter one or two vampire decks every time I played in a modern tournament.
A card you can also look at would be "Captain of the Watch". He doesn't exactly fit into your wheenie deck, but will push all your soldiers and come with three little friends

First I would Change from "Kazandu Blademaster" to "Elite Inquisitor". You don't have enough Allys to make him really work well.
Think of decreasing the numbers of "Mentor of the Meek" and "Thalia, Guardian of Thraben" from 4 to 3. You really don't want two of them in your Hand and also not on the board.
With the places won from this, you could increase the number of "Aether Vial" to 3, so you have a Chance of really drawing it, when you need it.
Interesting for all white decks who can't get some trample enchantments or equipment is "Brave the Elements". Your enemy won't be able to block your creatures this turn, you can avoid point removal spells and some mass removal like "Deals X damage to all creatures"
