is tapped in alt mode, and Rum-Maj is in bot mode with Sidecar Artillery in her weapon slot. I attack with Rum-Maj, adding her to Greasestain's station. Does the Sidecar Artillery trigger?
No. The attack order with stations is to declare attacker, declare defender, take attacker station, take defender station, and only then to do attack triggers. Greasestain
's station has increased Rum-Maj's attack to 4, missing the Sidecar Artillery trigger.
This Stratagem primarily exists as a teaser for future new mechanics. The Vehicle descriptor does not currently grant any additional abilities beyond what is stated in the reminder text. When this is flipped, return a Sidecar Artillery from your scrap pile to your hand. This can only happen once per game.
