I love Karn. He was created by Urza to b experiment with time travel. He later becomes part of Urza’s Legacy Weapon meant to defeat Yawgmoth. He also created his own plane that would eventually become Mirrodin. He reminds me of Data from ST:NG in a lot of ways.

I just know they were cool. Teenage badge who still played liked the idea of Weatherlight. And then the realization I would never be wealthy enough to keep up with everyone else. And thusly - D&D started!
