I've only tried it once, so I can't say I'm an expert, but I just find that summoning Whiskey Gamin is much more work than seems reasonable. You need to:
Activate the Porkchop first, so it can drop a scrap
Get at least poison 3-4 on Cooper, which is probably 2 activations
Summon with an 8+
That's at least 2 activations and probably 3+ AP, just to get a Gamin. It just seems like one too many hoops to jump through.
Maybe Sparks is worth the extra cost? His new "Now Yer Robot" seems to work well with a Gamin's Hard Slam
That being said, would it be better to run a construct list with Mah? Sparks, Survivors, Porkchop, and I think the Golem is still worth 10+1. Maybe some Test Subjects. Everything has armor except for Mah and Sparks.
