When using Zocc on a Thunder Unicorn, the mindless attack will “reflect” when the unicorn attacks itself because it’s blue on blue. I kind of get that logic; however I feel it is incomplete as it does not reflect anywhere.
In my opinion of logic it should reflect upon itself and cause damage to itself since it is the one attacking, just as if a blue hero tried to attack it and receives the damage it tried causing.
The other option would be to reflect the damage onto Zocc since he originated the ailment. But since he is not blue, it would not be logical to reflect the damage onto him, in my opinion.
Therefore, I feel that the Thunder Unicorn should incur damage when it mindlessly attacks itself by receiving the reflect as the attacker of itself.
