My other post was merged here and is buried.
Using their fonts, I tried to guess what it says...
The letters I'm guess are 'D_ _ t _ _ 50 B_ ild_ _ H'
So... try filling in the blanks. Only phrase i can come up with is 'Destroy 50 Builder H' is what I come up with. The Original Union Buster says Builder's not Builder and the 's makes it too long to fit. Also, the number 50 is too low for a 2nd star on destroying builder's hut. So maybe it eludes to something else regarding builders?
