Playability:
Difficult to understand at first but once you play around with combos it's quite enjoyable. Would do well with visual and auditory indicators of combinations to teach the player what is working well.
Theme:
This doesn't tie in with the theme well despite it being a fun submission. Don't stress it!
Cleverness:
Really love all the combos, elements, and switcheroos in these cards. You've done a good job making this complex and interesting.
Artistic Style:
Simple and consistent which is great. Would like to see simple effects for combos.
