Protip:
Not all status effects end when the turn is over.
Acupuncture, Poison, Ignition, Paralysis, Tag, these tend to end at the end of the turn (or at least count down) and apply their effects.
But Immobile or Chaos do not end at the end of the turn unless you've lost an action to them.
What this means is that using your Ino or Shikamaru at the BEGINNING of the turn will cause the enemy to lose their attacks/jutsu chance THAT TURN and just sit there. The effect will wear off at the end of the turn. But if you use these traits AFTER they attack (i.e. their turn has come) then the effect will carry over into the next round, allowing you to shutdown NEXT TURN'S jutsu or attacks.
Proper timing is very important to a control player. If your enemy has already performed their jutsu (usually because their initiative was higher or they were in the front row), using Shikamaru may be a waste as it only counters a single autoattack that round. But if you wait for them to attack then use Shikamaru, they will lose their chance to use a jutsu NEXT round, shutting down an annoying person's predicted jutsu and potentially giving the enemy nothing to cast that turn. This is especially effective against Fire ninja mains.
PS - Immobile also causes automatic defense like Neji or Hinata's rotation or Kimimaro's bone wall to shut off.
