I see that it is intendet that adrenaline prevents creatures from beeing freezed although its technically not three turns but three attacks. But when an sundial is up, no creature should attack and the creature with adrenaline still break the ice. is that a bug??
and why should i not be able to remove adrenaline with lobotomize?
You should be able to remove adrenaline with lobotomize, but for some reason it doesn't work. This is a bug that needs fixing. The Freeze/Adrenaline under Sundial issue you addressed is a symptom of a misunderstanding of the difference between an attack and an action.
When you end your turn, each of your creatures performs one action. An action causes the creature to attack if the absolute value of its attack is greater than or equal to 1, activates any triggered abilities local to that creature (e.g. Bioluminescence, Pest's ability), and activates any non-local effects triggered by creature actions (e.g. Empathetic Bond, Freeze, Infect). Thus, an attack is only part of an action. Since Sundial only prevents attacks, cards like Empathetic Bond* are still triggered, infections are still applied and the freeze counter is still decreased. Because Adrenaline adds actions and not just attacks, everything that is affected by an action is affected multiple times depending on the creature's attack power.
*Empathetic Bond is not affected by Adrenaline, because Zanz decided to make it that way.
EDIT: fixed the attack qualifier to greater than
or equal to.
