Warning: I build most of my decks using a mathematical formula (I almost never have to mulligan), flavor and tribes, and most importantly: power. My decks have also been built to accompany, offend, and defend large multiplayer games. My college-aged playgroup consisted of 5/6 Free-for-All/Pentagon/Emperor games and my current group primarily runs an average of 8 players in typically man-for-himself format. I don't usually play in competition.*
I was only 10 when Urza's Block concluded. I didn't start playing the game until I was 15 in 2004. Aside from A/B/U Limited, IMO, Urza's is the most powerful block in MtG history. There were a lot of cards from those sets that I was interested in playing, and a lot of them blue, so I decided to make an entire deck from that time.
The big guys are all free, and while Archivist and Disruptive Student may not seem like much, they do pay dividends. I was too cheap to buy a play-set of Gilded Drake. I have 4 Morphling in another deck and opted not to include it.
All support spells are creature tolls and counterspells. It's a fun deck to play.
*However, I have, and most shared decks are Legacy legal.
