Hello everyone.

what are the best packs to buy for unlocking weapon upgrades for these zombie charachters

Sky Trooper, Centurion, Sanitation Expert, Landscaper, Paleontologist, Archaeologist and Wrestling Star

I bought 3 vengeful zomboss packs but i didnt get a single weapon upgrade for these characters above
