There's only one strategy : patience. You will just have to collect as many packs as possible  (btw normal mode gives 20 stickers at best),  so you can get a figure of the packs you will need to complete the album in the ideal way (ie all stickers are unique). I bet there's someone out there with a better understanding of math to calculate the number of packs you'll actually  need. In short, I don't think you'll be able to complete any album without buying packs
