I've noticed this since the update patch [the one in February]. Everytime someone casts the Snow Angel spell the enemy casts there spell while they take the ice damage.
What i mean is this: Over the course of the three rounds of damage the enemy casts there spell WHILE there still being damaged. Now the same implies for if the enemy is defeated before the three rounds of damage is done.
I have a similar problem sometimes when I lag a bit and the spell appears in the card choosing point of view and just attacks fast. The solution is just to ignore it's nothing major.
