Unless it's a tournament, you can just make proxies and have as many copies as you want.
Make some proxies, this is what I do.
But, we still don't really know if these will be universally desirable. Their 0 attack/1 defense may mean that they get killed rather easily, or maybe because they only have one hammer they aren't that hard to block.
The command struggle happens before combat, so there attack and block have no meaning in the sense of how their ability is used.
