A couple of things. First, you have 98 cards instead of 99 or 100. I'd put in an Arms Dealer , just for more fun filled times. Second off, how does anything get played after Worldfire hits the battlefield? All permanents, hands, and graveyards get exiled when it hits play. You would need to worldfire your own Oblivion Ring that is exiling an Inferno Titan , or suspend both Worldfire and Inferno Titan and have the titan hit play one turn later. Other than that you can't do anything after that reset.
You do know that Mana in your pool stays also There is 100 Krenko is not in my Creature section. Also I forgot I have a Mogg Maniac in there which is better in my opinion. But back to the Worldfire pretty much I keep a extra 6 mana in my pool to recast Krenko. Also if I had flash creatures I can also stank stuff all day then play Worldfire. BTW I edited it Mogg Maniac is in it.
Shared Animosity would be a great card for this deck
Umbral Mantle and Mana Echoes makes Krenko arbitrarily large with arbitrarily many 1/1 dorks by his side. And if you decide on running Mana Echoes you should probably put in Comet Storm to just end the game. Door of Destinies and Coat of Arms will win you games unless your opponents have an answer. You should also replace Goblin Lore with Slate of Ancestry and maybe add a Reliquary Tower to your mana base so you can draw your deck and not discard. You'll also find that cards like Goblin Arsonist , while great in any other constructed environment really don't have the legs to shine when your opponents are consistently playing fatties like Akroma, Angel of Wrath or Consecrated Sphinx and start at 40 life. I guess you can get tricky with Goblin Shenanigans and Goblin Bombardment for 3 whole damage, but if that's the combo you want just add Kiki-Jiki, Mirror Breaker and Lightning Crafter .
Jar of Eyeballs , Umbral Mantle , card:Devil's Play, Comet Storm , Deathrender , card:Akroma's Memorial, Gamble , Sol Ring , Lightning Crafter , Kiki-Jiki, Mirror Breaker , Thornbite Staff , Shared Animosity , Mana Echoes
Cavern of Souls is on its way. Thanks for the suggestions but I'm kinda keeping true to the goblin nature on this one which is fast and speedy I usually have some one gone on turn 5 and another on turn 6. I like the suggestions I'll keep them all in mind :). Also Coat of Arms Was in this but it never seen play now Eldrazi Monument its seen play a couple of times and I've been very please when it hit play.
See I'm not look for infinite anything with my Goblins, lol. I came into this idea and just doing what Goblin nature calls, lol. Which is blow stuffs up (Including myself sometimes) or Swarm you very fast and deadly. I can't count on Mana Echoes and 1 artifact to do any of that. I really do like the idea of it I do thanks for the hint :D. But I'm probably gonna do that idea in a deck I can tutor a hell of alot easier in such as Red/Black with Rakdos, Lord of Riots >:3 Muhahahaha!!
