Pets/Mara

Strategy
In the tower, her green skill, Mind Control, activates at 12 seconds of battle, which is 1:48 on the battle clock.

At the time of writing, in guild battle testing, this same skill activates at 22 seconds of battle, which is 1:38 on the battle clock.

In addition to delaying ults, forcing the charmed enemy to use a basic attack against other enemies, and forcing the charmed enemy to not attack Mara's team mates, Mara's charm is timed perfectly to cause enemies to use these skills at least once in battle.

It should be noted that Lucas can be charmed while in rage form.
