Alarm-o-Bot died way too early, got only one Alert! on Scar. Had to finish Scar off with a Wind-up/Supercharge/Wind-up combo from my Iron Starlette, and had enough health left to charge up a Wind-up during Scar's undead phase and hit Little Blue with the follow up. My last mech finished the fight with a basic ability.
Scars did die at first wind-up, My iron starlette (H/H breed) had not died yet so when blue came in i used super charge and then wind-up again and blue kicked the bucket... never even needed my third pet.
Glad to hear that the strategy worked, but a little sad to hear that your P/B Starlette dies before it should. My Starlette is a H/P breed, and though both have the same power, your's is slightly faster, where mine has around 80HP more.. which could make a slight difference.
