Decided to get back into collecting pokemon cards. I may have overdone it a tad

Used to have a collection as a kid, and like most ppl, regret losing track of it over the years. So im getting back into it since its never too late. Now the only problem is how long its gunna take to open all of these. Right now im at 420 packs (lol). Was thinking about maybe doing a live and opening them all. Theres gotta be something cool in there somewhere
