The plan is to have Calgar - Null/Gate Libby - 8 TH/SS termies walking with the Scout Bike Squad making a scout move before turn 1 to allow a turn 1 Gate of Infinity to get all the termies in your face with 2 drop pod Iron Clads turn 1. If I am playing against ML spam/Oblits or equivalent I have 2 scoring fast/skimmer vehicles that can be used to tie up squads or reserve for later turn objective grabbing, they also come equipped with MM LS Storms. The drop pod tac squad can be used to grab objectives in the middle of the board in later turns while being able to combat squad with 1 MM squad and a melta/combimelta powerfist squad all scoring. The 10 man sniper squad is a "home-objective" holder that can aid in dropping high toughness squads or MC's.
The idea behind it was not necessarily a "Massacre Fest" list, but one that would be very difficult to beat and fast/versatile enough too be able to pull out wins in later turns. Not to mention I have 7 meltas/combi-meltas and 3 MM's.
