In mahakam, I've added to additional pikeman (for a total of 5) One pikeman in hand the 4 in my deck and upgraded to pikeman+

When I play Eyck, eventually followed by my one pikeman to the left of Eyck, it'll pull the 4 pikeman from my deck.
However, the image on the 4th (second from the right) is another Eyck! When I roll over with the mouse the description is still that of a pikeman. This happened at least in three diferent battles.

I think I've even seen Eyck when I play the pikeman to the left of another card... But cannot remember precisely.
