There is going to be a high opening market price once it is out this always happens in the first few hours of it returning to the market and slowly drop to my guess 100-150mil, but only if it doesn't pull a fast one like 1 week till mt. The cr announcement suggests that there is potentially another mt announcement ready, but I feel its more likely to be just Mechakolos Cr or both will go mt over Pandemos Cr.
Unless they make a 3 way monster battle event then it is pretty much guaranteed Nightmare will win when they have a huge advantage over Gheist and Paradox since they have had made unfair clan battle events before. I still haven't forgotten the highest damage event for miss. clint city Ghostown vs Pussycats.
