Obligatory Valakut, the Molten Pinnacle ? Hall of the Bandit Lord is good for hasty Krenko. Goblin Assassin is basically a board wipe every time you activate Krenko.Also, Shattering Spree is usually better than Shattering Pulse .

Goblin War Strike

I will be using all of those suggestions by you two, except for the Hall and Shattering Spree. Thank you.

Howling Mine just to keep your hand full even it is ony adding 2 more cardsThis deck could use some draw power

Reforge the Soul can be played for cheap and this type of decks its likely you dont have any cards in hand when you use it.

I don't like those cards because it allows my opponents to draw as well.

I would strongly suggest Coat of Arms and maybe even Eldrazi Monument just to buff up your goblins even more, cool deck though

Door of Destinies

Door of Destinies doesnt work as well as you would think, there are only like 15 cards in here that would activate it. and Eldrazi Monument/ Coat of Arms are SUPER expensive. Thanks for the suggestions!

If youre worried about cost use Brightstone Ritual and maybe even Seething Song .

Not worried about mana fixing. Thanks for the suggestions.

By expensive, I meant real life money.

Maybe add a Trumpet Blast

Deck looks really fun and i already have a lot of the cards including suggested cards like Coat of Arms so let the building begin.

Rings of Brighthearth is another good addition to Krenko's ability on top of the Illusionist's Bracers . Additionally, I'd consider Blood Moon to capitalize on the mountainwalk you're getting from Goblin King and Vicious Shadows , as you can just wipe your own board with something like Blasphemous Act and kill everyone off that way.

The ring and the moon are both GREAT cards but they are just simply out of my price range. Thank you for the suggestions.

I'd suggest Shared Animosity and try out Goblin Rabblemaster again. He doesn't have to attack and if you play him correctly it's hilarious. Goblin Bushwhacker - Haste. Goblin Lackey Warren Instigator for free goblins. Goblin Tunneler to make it happen.

Here's my current build for more ideas:

Goblins and Shiny Things. <{ Krenko EDH }>

Warren Instigator, Shared Animosity, and GoBlin Lacke are just too expensive. But thanks for te suggestions.

Goblin Chainwhirler, Goblin Trashmaster are both great goblins to consider.

A Blood Moon might be a good addition since you don't run any nonbasic lands, and it would totally ruin multi colored decks.

Caged Sun is awesome in mono colored mana decks.

Love Goblin decks, mine is called Pesky Goblins if you want to check it out. Best of luck!

You might want to consider revamping your mana base a bit. There's a couple of tricks that could help you take down the total number of lands in your deck while still improving your consistency, which would allow you to transfer some of your maybeboard to your mainboard.

Extraplanar Lens would be a solid pick for you since you've got so many basic lands to work with, but it's downside is that if your opponents use basic Mountains as well, you'll likely be buffing them as well. You can solve this pretty easily by swapping out all your Mountains with Snow-Covered Mountains. This will allow you to use Extraplanar Lens much more selfishly than you'd otherwise be resigned to.

Another nasty trick for getting those basic lands out on the field more consistently would be throwing in an Arid Mesa, Bloodstained Mire, Scalding Tarn, and Wooded Foothills. Using the abilities of each of these lands will thin your deck a bit and help with your draw reliability, and if you also add in Crucible of Worlds you'll be able to continually use any one of them to pull basic lands to the battlefield each turn if you need to. Having to worry less about mana means you can focus more on the good stuff.

I'm not sure of your budget, but a few cheaper cards to consider;

Citanul Flute (If the games go on for a while)

Dynacharge (Can actually be a game ender, at instant speed)

Goblin Chirurgeon (Saves half your board most of the time during a normal board wipe)

Breath of Fury

Wild Guess Tormenting Voice Faithless Looting Are all decent draw spells (For red) and help you to filter what you're looking for.

But one of the best investments would be Legion Loyalist It turns your goblins into first striking, trampling goblins, and who doesn't want that when they're 23/2's?!
