I really like this combo but to make it go off, I would suggest swapping Song of Freyalise for Cryptolith Rite.

Song of Freyalise only effects creatures you control at the time that the effect goes off, new creatures that enter the battlefield after the effect resolves will not gain the ability to tap for mana. This prevents your combo from going infinite.

Cryptolith Rite gives your creatures the ability tap for mana at all times.

Awesome! Powerful and low budget (for the type of deck).

Spellstutter Sprite?
Drop lands?

I am very excited how you use Liquimetal Coating and Master Thief together. However, because these cards do very little by themselves, I think that they won't do much for the deck. Master Thief needs more targets to be viable. I may have to steal him for my defunct Liquimetal deck though...

I never considered Voidwalk before, but I admit that I find it very intriguing! Voidwalk likes two things: 1. enter battlefield creatures 2.evasive creatures. How about creatures that are both!?

Baleful Strix (two colors, evasive, and a cantrip. No longer costs two arms and a leg to buy)
Liliana's Specter (the crowd favourite)
Nevermaker (like a reverse chittering rats with flying)
Shriekmaw (a more-different skinrender)

Training grounds helps. Typically about as much as an additional land... but one mana for extra land is pretty good. It gets better when you use the abilities multiple times a turn.

Not sure if it's much better, but "Prophet of Kruphix" gives you lots more mana on your opponent's turns.

Spire Golem is cool, but I am not sure how useful it will be in the type of deck you are making.
Other cards:
-Memnite
-Thoughtcast (probably worse than windfall)
-Tomb of the Spirit Dragon

a random Giant Growth could be a huge deal for Riptide Mangler or Tolarion Entrancer

Some neat cards I thought might be worth considering:

Cephalid Constable
Scourge of Fleets
Aether Adept
Phyrexian Ingester
Quickling
Nevermaker

I totally dig some of the choices you made for this deck. You didn't go all the way goblins; you put some game-winning red spells as well. The deck becomes a lot more diverse this way.

You have evasive creatures that get pumped from having lots of goblins. Beautiful way of making your threats more difficult to deal with.

All the haste you can fit in basically. Important for Krenko's ability.

I do have a couple of suggestions that may require a second look:

Gempalm Incinerator
Quest for the Goblin Lord
Chancellor of the Forge
Urabrask the Hidden
Hammer of Purphoros

Thassa, God of the Sea also has a surprising synergy with almost everything in this deck. Although, a one-of would double the value of the deck

Also, considering you have gone to a lot of trouble to activate Stormcaller of Keranos on the cheap... it may be wise to add some dual lands that tap for blue.

At the moment, all the ideas are super-special-awesome, but you may be trying to do too much.

I love some of the choices you have made.

The Opalescence is an interesting choice considering you don`t have many enchantments or other white spells...

Judge Unworthy and New Benalia might be useful inclusions?

I steal the Thunder AND the Lighning

Prey Upon + Obliterator is just too evil

You don't even have to win the fight.

Magus of the Vineyard maybe. Too symmetrical.

Maybe, not enough spoiled yet to see. However, Prophet of Kruphix may be worthwhile for the mana ramp.

It be definetly the Simic God. Right thar in the deck descraption

I like it. Maybe a fabricate to more consistently grab the cannon?

hmmmmmm......
DONE

Noted! I actually have used those cards in the past, but completely forgot about them when constructing this deck yesterday.

Early playtesting has determined that this deck has mana base problems. Trying to avoid Ravnica shocklands. Looking into cheap mana-fixing solutions:

Abundant Growth
Utopia Sprawl
Birds of Paradise

Suggestions welcomed.
