You can obtain one in Eterna City, one from Rowan's assistant after seeing 35 Pokemon, and one from the Jubilife lottery. You can get more if you have other Pokemon games like the GBA games you can use the Pal Park with. Give the EXP share to the Pokemon you intend to transfer. You can get many that way.
