Negative synergy? I prefer controlled chaos.
Let's get the obvious out of the way first: Ekomind and Levy do not play nice. Once you clear your hand with the LARLA, your MU drops to zero, but the recent ruling from Lukas states that Ekomind only sets your base MU. With 3 Akamatsus on the table, that leaves 3 MU for Origami.
Here's a deck that's meant to be played pre-paid Chaos Theory style. It wants to make two passes; the first is meant to take only a few turns, and it should be pure econ and establishment, while poking around to force the corp to rez ice, and we're playing our girl Quetzal who loves to run early and run often. Dig deep with Duggar's, install your e3, set up your Prepaids, work at your Day Job. Get your Same Old Things ready to fire. Ditch everything else that isn't draw or money. Don't be afraid to keep up some pressure with Overmind on the first run-through, and then overwrite, because you'll just be getting them back on round 2. Once you've Duggar'ed your way into most of the good stuff, drop the hammer; it's time to Levy.
On the second, it's pure pressure through events and Keyhole.
Break through barriers with your ability and e3, Overmind for the code gates, and Mimic for that Swordsman that will wreck your day (corps are going to start running a lot more Swordsmen. I promise). Along the way, Planned Assault out the utensils to melt away whatever it is you don't want on the board anymore.
