I'd pick up the cut block. LG have a lot of trouble in pass protection, I don't know if you can cut block pass protecting, but it would help. Foundation would probably be best, or hold block.
I have the money, just wanting to know if it would be a good one to use. Thing about the cut block one is that I have another piece with a +1 strength +1 Shock Block that's in the same slot. I have 24 tokens in that shock block piece.
