While I'm not convinced by the Darth messing the kill + changing claim as evidence of him being scum I do think the claimed kit (iirc 1x Gladiator, 1x Nexus, 1x Ascetic) can be taken as an alternative for Godfather/ Ninja.what makes you want the lissi wagon?
Nexus and Ascetic make so that user is somewhat immune to investigations (both alignment cop and motion investigators). Gladiator is fairly odd for mafia to have, but depending on how investigative results are presented this can be used to benefit from an erroneous investigative result to push for a high-risk/high-reward mislynch.
