from primary 6 till poly.
i still have some decks, but stopped playing already.
haha. my decks were:
Opal deck - most of my creatures are enchantments where whenever an opponent plays a creature, my enchantment comes into play as a creature. its supplemented with mother of runes, wall of light and enchantment destroying spells. my combo is during late game, i play a wrath of god, destroying all creatures, then playing this spell which brings back all the enchantments from my graveyard back into play as enchantment, so that when my opponent cast any creature spells, i can finish him off.
Phyrexian deck - basic creature destruction deck.
Rebel deck - Just overwhelm the opponent with creatures, takes a long time to build up force.
Counter control deck - Quite standard.
Coalation victory deck - goes together with my sliver queen to win the game.

obviously my fav is the opal deck.
