>>34691506I wouldn't recommend trying to get them from packs, you should try trading for them instead. Dark Patches are going to cost ~1-2 packs each. Dowsing Machine is like 6-8. Hoopa-EX is pretty important, it's about 2 as well I think? Lasers are about a pack each. The rest can be traded for with Pika Packs or other items/supporters if you're patient. If you'd rather try your luck at opening them though you can look up the names of the cards you need at
pkmncards.com it will tell you the sets that card was printed in.
