Earlier I mentioned that I got some Centaurs, from the Egyptian Cavalry set. Officially these are known as Centaur Chargers. I bought 2 packs of this Cavalry set, which gave me some 10 Centaur Chargers. That is 5 in each box. I also got an Extra from a Arcane Legions, League Booster Pack. This one prepainted (or factory painted, if you like to call it that.)
Yesterday I got a few more Centaurs, this time Centaur Archers, as they are officially known, in the Arcane Legions Booster Brick. You get 6 of those, in each Booster Brick, all prepainted.
You also get the hero Achilles from the Booster Brick. He is a "rare" figure. You get 1 rare figure, and 2 units of Uncommon figures in each Booster Pack. Achilles if you remember the greek fables correctly is a Human, not a Centaur, but the card that comes with him explains, that he is the reincarnated hero, or claims to be. Here are a few pictures of him.
