I use him in marker-heavy scheme-pool. My favorite models are wokou riders - they are mobile and resilent. Plus they have built-in Drop It! trigger. Main idea: Wokou Riders drop enemy markers in right places, than Parker convert it in friendly markers. You can take Aionus for more marker's tricks. Also, wokou riders can hit hard. They are can make Public Demonstration or Hold Up Their Forces too. For beater I take Mad Dog/Hannah/Sue/Johan/Alyce. Parker have a lot of SS and Dog, Hannah and Alyce would shine. Parker itself very mobile master and can do Undercover Enturage easy. I also take Hans in some rosters for vendetta, or he can shoot into engagement without randomize - Wokous go into engage, Hans make pew-pew-pew. Midnight Stalker for Covert Breakthrough or Surrond them.
