Why not Infinite Reflection instead of (or alongside) Clone ?

No Warren Instigator ?

Your deck needs work, so that it can be more focus on getting your win condition out and working. Since your win condition is Krenko, Mob Boss and Reckless One , you should have 4 copies of each.

I would say switch Goblin Lackey with Warren Instigator , its a cheaper card to buy, and its a better card. You can drop two goblins because of its double strike, plus more dmg makes up for CMC 2 instead of 1.

what ever cards you want to have in your deck, you should have 4 copies to increase your chances of getting the card as quick as possible to win faster. For instant you should have 4 Krenko's Command , it helps with both your many cards be more effective. Plus, gives you plenty of blockers and dmg output until you can get your win condition out,

drop the Goblin Rally the 5 CMC for 4 goblins is not worth it.

add in some cards that give haste. Swiftfoot Boots is a good card that gives haste and hex proof towards important creatures such as reckless one and krenko. Fervor is good also as you plan on having hordes of creatures on the board.

If you actually want the deck to be modern, instead of causal look at the illegal list of cards for the format as you have plenty that are illegal.

fill up your sideboard with cards that will help you counter decks that are common that you could potentially play. Cards that help deal with Enchantments and/or Artifacts are recommended. If you play allot of control decks, any type of counter spell would be good.

In the end you want your deck to be geared towards getting your win condition out on the field and winning you the game, having a playset of cards will normally be your best move. Also I don't know who you play, or how often, but knowing your opponents or general/common deck layouts will help you construct your deck to deal with a variety of treats.

Bowl. Goblin Lackey is amazing and you are wrong. Warren is not a better card, when Lackey allows you to start dropping huge plays on turn 2.

Anyway, do you want this for modern? Cause currently it uses legacy cards.

I've got a goblin deck you might be interested in. It is modern legal and aims to resolve either lords or value to win, with krenko as 1 off.

Bowl So I took your advice and I critiqued my deck to create a more straight-forward winning condition. Essentially, 4 Krenko, Mob Boss , 4 Reckless One , still 4 Goblin Lackey because its awesome, 4 Goblin Warchief and 2 Goblin Chieftain to give all goblins haste. Thinking about some hexproof artifact...any suggestions. Otherwise its going to be fun.

Good artifacts that give hexproof, Swiftfoot Boots and Lightning Greaves . Plus gives haste.

Now that you have multiple Krenko, Mob Boss you can play one, activate him. Drop another, sacrifice the tapped one to the legendary rule. then activate the new one, because he has haste because of one of the things that give haste. Thus Quadrupling the number of goblins you have in one turn. The Goblin Warchief makes doing this cheaper, and the Clone allows for more consistency with this possibility.

if you have money drop all the Island and Chromatic Lantern and put in 4 Steam Vents for a modern format.

for modern swap Brightstone Ritual for Battle Hymn

Question again, what format is this for? as I can help more if you tell me which format this is for.

Is this supposed to be a modern or legacy deck...?
