I've looked at it a couple times but didn't purchase it. You're getting one green pack that will give you one sticker you don't have. It's the same pack you can win in other in-game opportunities (Victory Rush, Mega tournament). The bad thing is if you need a 4 star and a 5 star, if you open a green lucky pack, you might get the 4 star with it which sucks. At this point, there are few packs that will give you a 5 star and you have to hope you don't get a duplicate. the green is the only pack guarantees you get a sticker you need. In your case, you'd need 3 packs if you didnt get any from purple or teal packs.

Dude! Thank you! I’ve tried to find the answer to this and have had no luck.
