Buying booster packs is an extremely expensive way to get cards!! I do not recommend buying them, especially at retail prices!
You can build a great and cheap deck from eBay and spend 75% less than buying boosters at Wal-Mart.load of bull, I built rayeels based off of tins and boosters for only 100$, e-bay does it for 150, and troll n toad 170, so load of bull
Unless you just enjoy the feeling of opening a pack and hoping for something good, then you spent $5 on worthless.
I'm more of a facts and logic person and I don't like throwing my money away.
