Lucky Patcher is used to bypass application security, basically for pirating, and cannot be discussed here.
"Lucky Patcher is a great Android tool to remove ads, modify apps permissions, backup/restore apps, bypass premium applications license verification -- This is a no-go here - , and more."

You don't root an SD card, you root your phone.
