Through the kind help of others (and no small amount of currants spent), I have achieved the two Cubimal Wrangler trophies. If you are missing any of the following I am willing to accept any reasonable offer (and maybe some unreasonable ones)
From Series 1:
Uncle Friendly
Yeti
Magic Rock
Greeter Bot
Rook
Juju
I have all of Series 2 except Hell's Bartender, including duplicates of Scion of Purple, Trisor and Meal Vendor
