I'm not particularly fond of the berries thing, not when there's the whole "2 DP for each main deck card", which for me discourages from making mixed decks and sticking only to decks that uses one type of berry (+ Enigma), rather than risk my already bad luck in getting cards that requires other types of berries.
Maybe there could be a mode where berries works differently, like the pokemon's main berry type boosting them when they are placed on that field and any other that isn't Enigma weakening them instead.
Glyphs are also another thing: I don't feel encouraged to rely on Glyphs AT ALL other than Memento, Tenacity and Lucky on obstacle cards (Rocks, Trees), due to increased Berry costs on glyphed cards. Maybe there could be a different approach: 1st glyph has no increased berry cost, 2nd glyph has increased berry cost, 3rd glyph changes the 2nd berry cost to Enigma berry.
