I've been trying to get 3x of each enemy card (can't use cheats because they give me 98, inlcuding the Boss ones). Now, I have been pretty patient with some of the randomness of the drops, such as they vary between 2 battles in a row to not dropping them in 2-3 hours. I also figured out that the type of enemy card dropped depends on which enemy you defeat last in that particular wave, which helped me quite a bit. But now, I've been fighting Barrel Spiders continuously for over 3 hours, and they have not dropped one enemy card. I wonder if any of you have suggestions to overcome any further difficulties with this. Right now, my strategy is as follows: 1) Use Sleeping Darkness map card. 2) Attack the 3 barrels within the small proximity. 2a) Fight the Barrel Spiders 3) Repeat. If nothing is there, it usually takes me 15 seconds per room. T_T Edit: v_v... After I decided to take a break from this crazyness and try to get a rare Simba card that probably wasn't going to appear, I got a Simba 0, and the next Barrel Spider I fought, it dropped the enemy card... I don't know what's going on anymore... @_@
