If you wanted to increase the chances of Shikamaru's crit -> immobile, Tenten would help you accomplish that, as she buffs crit rate for 2 turns at 2 stars. That would allow you to control without using Mystery or Chase.

Tenten's Passive at the bottom states that she increases the crit rate of her team for 2 rounds. More crit % = more chance to crit. More chance to crit for Shikamaru = more chance of immobile activating. Either I'm reading Shikamaru's skill wrong or it's bugged.
