Cut Reckless, Stentch, Earwig, Brightstone (10 cards); Add 4 lands or landfetch (armillary sphere and the like), 2x Burn at the Stake, 2x Mogg War Marshall, 2x Beetleback Chief, 2x Altar's Reap. Buy it.

Let's talk synergy. You've nothing worthwhile to champion with your Lightning Crafter. Where's Beetleback Chief or Mogg War Marshal? Championing a token for a better creature is nice, but why not champion somethign that benefits from coming back into play later? Voracious dragon does the same thing only backwards. Sure eating tokens is fine, but why not have stuff that does stuff when it dies? Goblin Arsonist or Mudbutton Torchrunner work great for being eaten. Or being Goblin Grenade'd.

you should take out all the goblins and splash some blue for homonculusi (plural of humonculus).

I don't know what Caterwlwpgl;kj does for you. Expensive, easy to kill. Cut it. Reckless works, but it is a 'winmore' card. I mean, once you're big enough to kill someone, he would be big, too? When why'd you need him? The dragon is neat, but not as neat as something with conspire like Burn Trail or Giantbaiting. Truth is, how many tokens are you planning on eating? If less than six, Burn Trail is a better choice. Kind of. Artillerize is the poor man's Goblin Grenade. Oh you have goblin grenade? Uhm. Okay. Why not lightning bolt or searing spear or anything else? The rest I don't mind. Now, you need draw, because once you blow you load you are topdecking pussy 1/1s. The other thing you need is something to either a) make the toughness of all goblins better or b) something to push damage through or around defenses. Raid Bombardment is neat. Boggart Shenanagans may protect against getting wiped. Maybe.

I really like Lightning Crafter, I'd find a way to put him in. Caterwauling Boggart is kinda iffy, maybe switch them out?

Looks like you want to turn tokens into monsters. Some of these cards may interest you; Shared Animosity, Burn at the Stake,
Quest for the Goblin Lord, Battle Strain, Kyren Negotiations, Furnace of Rath or Soulblast? I think attacking isn't as effective as direct damage. I would keep what is critical to building a body of tokens and find ways to deal damage when either creatures enter play or # of creatures. Also, this mode will have you top decking faster than most decks would
