Key Interactions-
Goblin Grenade + Tuktuk the Explorer or Goblin Arsonist or Mogg War Marshal
Warren Instigator + Goblin Chieftain or Goblin Wardriver

This budget version of an old Legacy favorite works a little differently from the other goblin decks you may be used to. While the general strategy of swarming your opponent with little green men is still here, there are a few interactions unique to this version that are birthed from the inclusion of an old Fallen Empires card called Goblin Grenade. Turning Tuktuk the Explorer into a saboteur results in a 5/5 golem taking his place. Pretty cool if you ask me, especially considering that the golem is also a goblin, which means Goblin Chieftain makes him bigger. It also means that you can sacrifice him to Goblin Grenade as well, if you really need to.

While less awesome, but still cool, you can also use Goblin Grenade in combination with Goblin Arsonist for a bit of an extra effect. This is nice if you want to hit your opponent in the dome but also need to kill a creature threat. Still less awesome, but still kind of cool, is Mogg War Marshal, who replaces himself after exploding into what I can only assume is five pieces, one for each point of damage that results.

Beyond the cool interactions that come from killing your own guys, you have Warren Instigator. Now, in case you didn't know, Doublestrike on Goblin Lackey is pretty darn cool. One hit to your opponent is actually two, which results in a goblin spawning effect that I like to call The "Warren Instigator makes lots of goblins appear" effect. Hey, I never claimed to be creative. Coupled with this is the fact that Doublestrike means that this guy does double the damage of everyone else. If Goblin Chieftain shares the field with Instigator then you can count on him hitting for a respectable four damage. Add in Goblin Wardriver and you have a six-power creature for two mana.

Overall the deck carries some nice surprises. Five damage for one mana is certainly nothing to scoff at, as it is a full quarter of your opponent's life. Getting a 5/5 golem out of it as well is just the exquisitely tasty icing on the cake. I would say that for just $60 this is all pretty nifty, especially for a bunch of suicidal Dobby clones. (I don't care what you say, that guy is not an elf....)
