I Pulled this out of a table and made some changes outlined below:
1-I changed the size of the + and - buttons so they weren't as wide
2-I added the 5 buttons (four of them) to adjust the values by 5
3-I added the copy power to toughness button (->)
4-I added the copy toughness to power button (<-)
5-I added the clear (set to zero) button (x)
6-previously the tile reset to 0 when copied (the copy reset, the original stayed the same), all the code to keep it's values was there but wasn't active, I corrected it to work.

I would give credit to the original creator but I have no idea who that was... so I'm sorry for that and if you can link me to the original version of this tile I would be happy to add credit.
