This will probably not be the most competitive version of RDW to hit the table, through it's lack of consistency. However, if you want a combo style blowout turn 3, this deck might be just what you need!
=== THE MAIN IDEA ===
Here's our perfect curve; the one drop is optional but helps.
Turn 1: Foundry Street Denizen
Turn 2:
Generator Servant
, swing for 2
Turn 3: Sacrifice
Generator Servant
and play Goblin Rabblemaster + Goblin Piledriver; after the Piledriver's beginning of combat trigger, the Denizen is a 4/1; then swing. Denizen hits for four, Piledriver hits for 7, Rabblemaster hits for 5; 16 damage turn 3, bringing our opponent down to 2.
Turn 4: Lightning Strike, Stoke the Flames,
Wild Slash
,
Exquisite Firecraft
, etc.
Generator Servant
+
Goblin Piledriver
+
Goblin Rabblemaster
is good at any stage of the game, whether it be on a curve of Dragon Fodder --> Hordeling Outburst --> win the game, or whether you need a late game finisher. Servant is relevant even with just one of the two "combo pieces (especially piledriver). Unfortunately, servant can't give our one drops haste; worst case he's 2 power for 2. I think he could be decent with piledriver able to provide blow outs to tapped out opponents.
