Today I'll explain what CLv0 and CLv1 mean and also how to get those CL Level Ups. You have to have the green cubes to level up each Pokemon figure. Rare cubes can only go with rare figures, common cubes only go with common figures, UC cubes only go with UC figures, and EX cubes only go with EX figures. That only pertains to the green cubes for CLv0 to go to CLv1 and above. The blue cubes are for experience. The gold cubes are known as Ingots and they are traded in at the shop for gold. Be sure to trade those in for gold and don't fuse them.
