This is all about building an army, saving up your units until you have a line of Gangers. Try not to put down your blockers, those will be played for free later.

With Evelyn Park flipped and a line of Gangers, play something that will spend eddies, AND STEAL GIGS (don't forget your Solo's). This will untap and bunch of eddies, that's when you put up your line of blockers all for free.
