So this is how the fight was:

Turn 1:
My baba yaga goes first. I casted kid eater possessing 2 of his monsters (the other was timerion).
Turn 2:
Timerion casts Looped Damage
Turn 3:
His possessed minion hits timerion. The "obvious" thing would be timerion attacking back his own minion but for my surprise he attacked me!
Why? Looped damage mirrors attacks, how can it mirror at me since I wasnt the one landing the attack.

In another case now.
Hitting timerion with Looped Damage with an extra turn skill , grants timerion extra turn.. this is devastating. Why should the extra turn count for him also. Imo this is broken.
