Hi JJ,
The main problem for every Theatric is a War. Not a tank. But exactly War.
To be successful vs these Wars Your's Theatrics just needs relatively high Chi. Just to drop a War down, and then finish him.
There's no methods to drop down a War except Chi. (Or Signature Movies, but, You know, SM too random... )

So. Something about Agi/Chi = 3/2 .

// Although i [totally] do not like what You trying to build. But Your question is Your question. Have an answer ;)
