1) I already mentioned Parasite Infection combo being overpowered in previous posts. Parasite Infection and Elven Agility is totally over the top especially because it is Buff slot combo. It must be much much much more decent in regeneration reduction and bonus damage reduction.
2) Special card Prophecy is placing graphical effect of watching eyes in a little disturbing way. I would prefer to shift that graphical effect either above or under cards in hand to see which card is which just at first glance. Both for opponents hand (when my Shaman plays Prophecy) and for my hand (when opponents shaman plays Prophecy).
3) I mentioned before, that I like shapeshifting mechanic, but I am a little disappointed how both Bear and Jaguar forms are practically same. I would suggest bigger difference between them. If you look at "Brutal Grizzly" and "Brutal Jaguar" as the highest shapeshifting forms (combos), which are both composed by 4 cards, they are different only marginally. They both have 6 attributes, which are of same nature (basic damage, bonus damage, reduce opponents bonus damage, bonus HP, self damage and shapeshift).
I would suggest something like this instead ...
- Bear form and its combos, especially in final highest (4 cards combo) form should have attributes like basic damage (higher than Jaguar), bonus damage (higher than Jaguar), bonus HP (higher than Jaguar) and defense. (Plus obligatory self damage and shapeshift.)
- Jaguar form and its combos, especially in final highest (4 cards combo) form should have attributes like basic damage (lower than Bear), bonus damage (lower than Bear), bonus HP (lower than Bear), reduce opponents basic damage, reduce opponents bonus damage and regeneration. (Plus obligatory self damage and shapeshift.)
My reasoning for it is that ...
- Bear is strong and big (more than Jaguar) [basic damage, bonus damage], with higher endurance/resistance (more than Jaguar) [bonus HP, defense], but also not so difficult to hit (unlike Jaguar).
- Jaguar is agile and is generally not so easy to get hit [reduce basic damage] and even when he is hit, due to something like instinctive dodge [reduce bonus damage], he is not hit with full power and Jaguar is also from cat family, so he should have 9 lives [regeneration]

4) I think, that Orc Shaman skills are a bit over the top, but I will return to this later with more experience.
