To help me understand what you're looking for, could you please provide more context?
For example, tell me:
* What game are you referring to? Is it a specific board game, card game, video game, or something else?
* What does "pivot" mean in this context? Is it a specific move, strategy, or tactic?
* What do you know about General Grievous? Is there any specific ability, weakness, or strategy associated with him that you're trying to exploit?
Once I have more information, I can try to give you a more relevant and helpful answer.
