One of the first decks I ever played competitively was an artifact/red deck during Urza's block constructed that I had seen from him. He of course won the 1999 WC with a better busted version of it too, which I also built for casual play. I loved that deck and still do, some of the most fun I ever had was ramping into Wildfires and Temporal Apertures! I will always think of him when I think of those days.
I didn't realize just how much he was the GOAT too. 5 Pro Tour titles and *a World Championship. Absolutely amazing career and a truly amazing guy.
