I played a few games, long ago in the distant past.

still play casually every now and then. Never too serious. Great fun, just never had friends who were as interested in the game as me.

I played online drafts fairly regularly until around when 10th edition released.

long ago, never seriously

I used to play. My cards are in boxes, collecting dust; I plan to sell them when I have the time and inclination.
