The deck has many things to offer in a Mardu aggro/control. Its creature base consists of creatures that all have a major impact on board. From Frenzied Goblin and its ability to make an opponents creature unable to block, to Butcher of the Horde and its multiple abilities of haste, vigilance, and lifegain.
Notable Combo's:
Goblin Rabblemaster + Purphoros, God of the Forge : Because two damage each combat is fantastic, especially if their is more than one rabblemaster.
Goblin Rabblemaster + Butcher of the Horde : Being able to choose from Butcher's abilities each combat comes in handy anytime.
Twinflame + Goblin Rabblemaster, or Butcher of the Horde, or Stormbreath Dragon Because any of these copied are deadly and game changers. Rabble for it's multitude of tokens, pumping each other up for the swing, Butcher because 10 damage overhead is amazing. Stormbreath simply because 8 damage overhead with pro white.
Frenzied Goblin + Iroas, God of Victory + Any creature (especially Goblin Rabblemaster )) = Getting that damage through!
Generator Servant + Goblin Rabblemaster + Twinflame = Swinging for 12 on turn three assuming you have one more mountain up for the twin flame after summoning your first rabble for one mountain.
Generator Servant + Stormbreath Dragon + three lands = Turn three dragon for your viewing pleasure. :)
Aside from all of the creature's there is a fair amount of control in the deck.
Crackling Doom
Is amazing.. period. Two damage plus making the opponent sac his or her strongest creature is just to good. Banishing Light for those pesky God's or any other nonland permanent that isn't pro white or hexproof.
Mardu Charm
Because of value, 4 damage to a creature, 2 soldiers with first strike, or able to see and pick a card that isn't a land or creature from your opponents hand and all at instant speed!
Please keep in mind, the cards you see are the cards I currently have. The deck is always up for change if the need arrives. At no point in time will any of my standard decks have cards on the board that I do not own unless said otherwise.
