This one ought to be fun (and accelerate play for these quick server resets)
Pickaxe Snowballs! You have to have at least stone to even use it, and iron is more effective. Mines out non-ores replacing them with air. Increasing power gets bigger areas, begins to ignore stuff like coal and iron, then at crazy levels you can flatten the bedrock floor. At double nether star diamond (crazy OP) it removes the floor and leaves only void and the ores to stand on, which is hubris in action and just what ought to happen to anyone that OP. Makes for good traps, and the flat-floor version is good for bases :)
I don't think SwordSnowball is changed at all. I might have fixed a comment typo.
