Might as well post first!
A deck I played when Mirrodin first came out.
3 x Veldalken Archmage
2 x Words of wind
1 x Broodstar
4 x Thirst for Knowlege
4 x Ornithopter
2 x Brain Freeze
4 x Thoughtcast
4 x Seat of the Synod
4 x Myr Enforcer
4 x Frogmite
4 x Cloudpost
4 x Aether Spellbomb
3 x Welding Jar
3 x Echoing Truth
2 x Tooth of Chiss-goria
2 x Scale of Chiss-goria
Basic idea is you play affinity and draw cards with archmage until you get words of wind out. Using words of wind, bounce your own artifact to your hand and play them for 0 cost. In the end it equates to 1 mana to return 1 permanent of everyone else (who wants to do 8 way multiplayer with this deck?)
