Hello there !
Let me explain : I play magic since a while (I started with
Urza set). But back then, I was a teenager and I only afford some boosters from time to time. So I made deck with what I could found fo casual plays with friends and family. As there was very few player, I still have pretty low experience on deck and collection building.
Since a few years, I was wondering how to build a trading collection.
As for now, I buy the cards that I need for my commander decks. And I sometimes buy boosters or boxes. The fact is I have dozens and dozens of rare cards that hadn't interested anyone since years. And some of them with very little value and in multiple copy.
Sorry if it is a silly question for you, but are there any method or tips to build an attractive collection to trade ? Or it is just all about getting more and more boosters and having luck ? I'm pretty fed up with my binder full of 80% of trash rares xD
