New Deepslate tools at the Game

I would find it cool to add Deepslate tools, to add a new utility to it. -Deepslate Tools, They would break Deepslate with the speed of an iron pickaxe breaking stone, speeding up the process of getting Deepslate blocks. -Making a Deepslate Tool would unlock a new achievement named: 'Dark Mode On' -Deepslate tools would be slightly better than normal cobblestone tools. So these are my ideas about it, I hope the Mojang team like it!
