A friend of mine have cards from Revised (can't quite remember which block, it was the one after Beta) all the way to Mirrodin. Been dabbled around in Type 1 (vintage) and Type 2 (mixed). I started buying after Darksteel and stopped at Cold Snap.
Have tried Arcbound Affinity, Squirrel Opposition, Storm Desire, Revival (blue black, t2 Kamigawa based), Tooth N Nailer, Madness and a bunch of random deck with annoying strategies.
I still have my UB Revival, UG Madness and Desire deck for "serious beatdowns". For casual plays, I love my Ravnica block Niv-Mizzet Pandora deck. Its annoying as hell to shuffle and redraw 7 cards (for each Pandora's Puzzle Box) at each upkeep, but it pings away 7-28 damage per upkeep.

My glorious UB Revival:
4x Buried Alive
4x Animate Dead
4x Necromancy
3x Living Death
3x Kokusho, The Evening Dragon
2x Yosei, The Morning Dragon
1x Bladewing the Risen
1x Symbiotic Wurm
4x Rewind
4x Mana Leak
4x Counter Spell
a 50 card deck with about 16 lands. Mostly control based (sit back and turtle), winning condition is to swap Yosei/Kokusho for life drain or tap lock. 3 mana Necromancy (as instant) will save you from many sticky situations, reviving a 5/5 flying that wrecks the game when its sacrificed at the end of turn, or a 7/7 wurm that turns into 7 1/1s. It's over when you cast Living Death with Bladewing, two Kokusho and/or Yosei in the graveyard. Put the Bladewing's come into play effect on stack, sacrifice two Kokusho/Yosei due to Legendary rule, and resolve Bladewing's effect. You can either drain 10 life, or tap 10 targets and force your opponent to skip two untap phase, and still have two big dragons in your field to attack next turn.

Still trying to finish my Wake deck.
