Started playing back in the days of Ice Age, stopped shortly after 5th Edition. Lost a bunch of my collection I was selling on consignment at a gaming store that abruptly closed, so I kind of got out of the game in disgust for quite a while.

My trade list typically won't be more than a few things at a time - don't really buy a lot of packs these days.  Usually only looking for Standard stuff.

I ship USPS First Class with cards in penny sleeves and top loaders - typically with delivery confirmation if cards involved are worth more than $10 total.
