To be honest, I haven't actually finalized the list, but I have all of the cards for basically every version.
I have:
4 Blinkmoth Nexus (one in Chinese)
4 Inkmoth Nexus
1 Magus of the Moon
1 Blood Moon
4 Whipflare
3 Spellskite
4 Ethersworn Canonist
4 Dispatch
4 Thoughtcast
4 Master of Etherium (2 foil)
4 Signal Pest
2 Steelshaper's Gift
4 Arcbound Ravager
4 Vault Skirge (one Japanese)
4 Springleaf Drum (all signed)
4 Cranial Plating
4 Ornithopter
4 Galvanic Blast
4 Memnite (one Chinese)
4 Mox Opal
4 Etched Champion (one French)
4 Shrapnel Blast
4 Darksteel Citadel
I also have, for the Legacy version:
3 Tezzeret, Agent of Bolas
4 Frogmite
4 Myr Enforcer
4 Vault of Whispers
4 Seat of the Synod
4 Ancient Den
4 Great Furnace
3 Tree of Tales
With all this you can basically figure out as you go how you want to play. Note that three of the Ravagers are LP and I have owned many of the commons since middle school, so they have seen some love (LP/MP)
TCGPlayer.com puts the Affinity kit at $333.82, so I would be willing to trade it for a Tropical Island, 2 Bayou, a Taiga and a Jace, The Mind Sculptor. I'll throw in double sleeves (UltraPro art sleeves over close-fits) for most of them for shipping purposes/I'm too lazy to unsleeve them.
