Ooh, looks fun.
Trebuchet is an interesting counter to Antimatter -- who cares if your Doll has negative attack when you can just fling it in your opponent's face?
Chimera is an option for increasing the EM rate by comboing with LS. It's also nice to have when you can do enough damage to win, but haven't drawn a Momentum for getting past full-blocking shields (Phase, Wings, Dusk, Fog, Dissipation, and Gravity).
