I enjoyed playing the demo of Astral Masters and so bought the game to be able to play the Advanced League and to use the "bought-only" cards.
However, I'm seriously disappointed in the Advanced League. I expected some cheating in points used but some of the opponents use blatantly illegal decks. I played against one opponent (with 1215 mind for me) that used at least 8 Phantom Warriors (at 200 mind cost each) - considering those 8 showed up in the first 15 (maybe 20) cards, there were probably many more (when there are supposed to be max of 3 of any one card in a deck). Yes, those were cards drawn - no clones or abilities were used.
I know programming a good general AI for a game is hard but it really annoys me when game designers are lazy and have the AI blatantly massively cheat.
