In this datapack I made random size that changes every minute, I was surprised when I saw that there isn't this datapack on this site. It's very interesting datapack because you don't know which size you will be. Minimal size is 0.01 (but chance is 2%) it means that you will be smaller than normal player in 1000 times and Maximal size is 30 (chance again 2%) you will be 60 blocks in height.
I added that your size = your damage = your defense. For example if you are bigger than normal player in 10 times, you will damage mobs in 10 times more and get less damage (in 10 times).

After update: you break blocks faster or slower.
