Currently I'll have every Mage knight ever made if I can acquire these last few pieces. Obviously the sinister four horsemen poses a real challenge if not insurmountable. Also the battle force pack of Tal D'reen, Kithana of Uhlrik, Janos Freeborn, Vharigar and then Huntress Chela. So anyone up to trade/haggle price lol :)

There is a Tal D'reen up on eBay right now (I'm not the seller, just saw it while browsing the listings)

Update: all I need is Huntress Chela, the amulet shards from uprising and obviously the four sinister horsemen. Then I will have every Mage knight, I'll need to look at my LE list but I believe those are all done as well, even the rare mounted elf general and all rebellion LEs :)
