Played since 6th grade. The Tempest set was just released and where I started. Still has a warm fuzzy place in my heart.
Got a case (6 booster boxes) of Darksteel+2 other boxes from that block with some friends. Played booster drafts with 8 of us all weekend. Was a blast. Would like to do that again with an old set again. After the Urza block they just started adding all these various abilities and such (in addition to the old stuff) which IMO killed the game. My friends and I still play, but we try to just use old cards and decks.
Some of my fav decks:
Counter-burn (cheap/free counterspells+burns=fun. One of the most hated decks in my group of friends)
Infinite life gain- I forget the cards ATM, but basically sac x life to be able to create x/x tokens, sac them for life, put in another token generator with more life, rinse repeat.
Green stompy- Came from the booster draft, but uses Darksteel Colossus and 1/1 token generators then overrun FTW
elf deck- friend made a pretty solid elf deck
worm deck- friend made a fun to play deck using oath of druids+a card that when flipped into graveyard shuffles graveyard back into library
Sliver deck- slivers just are beasts
There were some others, I just cant remember. I'd be interested in buying some older cards if anybody is selling their old stuff (Urza block or prior)
