Creature didn't take damage
While playing the game, I summoned the Chandra, Awakened Inferno. I used the ability for -3 loyalty counters to inflict 3 damage to each non elemental creature. One of my opponents creatures, Legion Guildmage, took no damage even though it is not an elemental creature. It had a single +1/+1 counter on it from mentoring.
this i think is a log of it )(also effects didnt work on there creatures eather
