i started playing when Mirage came out and stopped at the end of the Tempest-cycle.
my gg-decks were these:
N1: Blue Control Deck - 4x counterspell, 4x dissipate,4x capsize,4x control magic, 4x clone, (and some more shit to fuck up your game: winter orb, icy manipulator)
N2: Insane Damage Deck - red/white - En-Kor creatures, 4x Shaman En-Kor, 4x Mogg Maniac, 2x Magmasaur, 2x Shard Phoenix, 2x Pariah, 1x Furnace of Rath, (more fun dmg / gain life stuff)
N3: Apartheid Deck - black/white - this is a lock i found completely on my own, it is usable only against creature based decks. it goes like this (in this exact order)
1) Darkest Hour - All creatures are black
2) Light of Day - Black creatures can't attack or block
3) Celestial Dawn - All cards that u own (in play, in your hand, in your library, all your mana, ...) are white.
it is funfunfun
it is also a knight deck so: 4x white knight, 4x paladin en-vec, crusade, jihad, balance (if it doesn't turn out nice for me
)
if you want i can post the full decks but i'm too lazy now...
