I've found this really easy way to set your whole crew on fire.
All you need is:
Kaeris with G&D
Carlos Vasquez with Practiced Production and Stund Double
A card with 7+ as backup
How it works:
Activate Carlos as first model.
Use Practiced Production to place one scheme marker within 3'' of as many models as possible. Make sure, all models are within 6 of Kaeris.
Use the (1) Pyrotechnic Prop to detonate the marker.
Forfeit the Wp flips (or cheat a small , for your Gunsmiths)
Enjoy your burning and flying crew. The scheme markers you drop at the end of every activation provide a great starting point for many schemes. Fast and flying Gunsmiths can move into position and shoot in the first turn. Raptors can drop markers within 16'' (i.e. the center line, enemy half of the table,...).
If you need/want to move Kaeris use (0) Truth in Flame to extinguish the models that have not activated and draw cards.
You can even use this trick to heat a Rail Golem. For maximum effect use The Captain and his (1) Airburst (best with the -trigger) to push the Rail Golem out of Kaeris and enjoy your rampage with burning 5.
I haven't tried Kaeris with Purifying Flame yet, but the potential healing could help to heal the damage Alpha Strikes.
Did I miss anything? Does it work that well for you?
