Im toying around with some monored build, too
here is what it looks like

// Lands
4 [MOR] Mutavault
17 [CST] Mountain (2)

// Creatures
4 [ZEN] Warren Instigator
4 [PLC] Stingscourger
4 [M10] Goblin Chieftain
3 [EVG] Siege-Gang Commander
4 [AP] Goblin Ringleader
4 [US] Goblin Lackey
4 [EVG] Goblin Warchief
4 [LE] Gempalm Incinerator
4 [ON] Goblin Piledriver

// Spells
4 [DS] AEther Vial

// Sideboard
SB: 4 [SC] Pyrostatic Pillar
SB: 3 [BOK] Umezawa's Jitte
SB: 2 [DK] Tormod's Crypt
SB: 4 [SOK] Pithing Needle
SB: 2 [HOP] Relic of Progenitus


As u can see, i run a straight forward aggro-plan. I cut all utility creatures along with matron. Matron is really to slow in this build. Also i run Mutavaults over Wasteland to get even more dmg to Opp Head. Runs really smooth so far.
