I work in a fast food joint.
Most of my mtg loot was obtained before I considered it expensive. Nowadays I trade/sell what I have for new cards. Mostly buy/sell on eBay to scratch the itch.
Just today, I traded away type2 bulk rares and uncommons for 12 BFZ packs and the first two packs I crack are a Prairie Stream and a Scalding Tarn Expedition. I'm considering just selling or trading away the other 10 packs. Not sure yet.
Mechanical Designer Engineer here. I started magic because I bought a shoes box for less than 100$ (years and years ego) with somethings like 8-10 dual lands. From there, I just fall into Legacy, and more recently into Vintage after a very good deal for a Black Lotus, Ancestrall Recall and Mox Saphire. I'm currently acquiring the rest of the power by selling some cards, mainly "Foil staple" that I lucky got from boosters
