Dude, I love the mammoth-mounted marro gunner! Do you know if they still sell those Yu-Gi-Oh! figures? I feel like I saw them at some point in time at Wal-Mart or Toys-R-Us, but that stuff changes all the time. I might make my own and come up with a custom card if you don't :P
That rhino is ridiculously huge, but I suppose you could call it "genetically enhanced" or something
I've got my own copy of Battlemasters, and we haven't played it since I was a little kid. If my dad isn't emotionally attached I'll have to repaint, possibly hack up the pieces and see what kind of customs I can come up with. First I need spare Heroscape bases, though... I really must get a second Master Set one day but I can't quite afford it at this time.
