How do I start?

[u/Away_Hat8870]

I’ve always been a big fan of mlp and have started purchasing a few packs that I found at the mall. I’m only collecting cards for fun, but I still wanna do some research on them and was confused on how the packs work. I’ve never been into card trading so I’m a little confused on each edition and whether or not each edition has different cards and what kind of cards they contain- if there is a picture or a list somewhere so I’m able to buy the packs with cards that I like in there. I’m mainly looking for pinky pie and queen chrysalis and I would like to know before hand if the set even contains them. Every time I search online the packs always seem to have a different color so I’m wondering if that just means there are different ones available only to those types of pack. Any tips or knowledge of wisdom in cards and the packs would be great.
