I only play cube and draft now but when I used to play constructed I played :black: :blue: mill decks mostly.
Scalplexus, Brain Freeze, Mischievous Quaner, Ravenguild Master: all great staples. Then when Ravnica came out it got even crazier. Szadek was a beast.
Also used to have an awesome deck based on Erratic Explosion, Torrent of Fire and Goblin Machinist. Plus all the big monstrosities I could get my hands on. Dingus Egg worked well in there too. mono :red: BTW
And I played :black: :white: clerics during onslaught of caurse cus they were the bomb and not as overused as the stupid elf and sliver decks. Desolation Angel made for a somewhat pointless but fun addition in Standard
