trigger help

I hadn't gotten a reply in the trigger forums for about 20-30 minutes, so I wanted to post here.
My game has a Death Form, where Death can turn into his true form, he's normally a Human like the real Humans.
Here's a summary of what my triggers are supposed to do:
You have a Human. He has the ability Death Form.
The unit uses Death Form. Owner of the unit changes from player(killer) to Player 12.(at the same time, player(killer) unallies all other humans) Now the unit is Death, Death uses Human Form to transform back, ownership changes back to player(killer).(player(killer) reallies everyone.

Player 12 is a computer made for the sole purpose of taking ownership of Death.

In other triggers, I have already made everyone unally Player 12, and player(killer) re-ally him.

Here's my map in case. The ally/unally category is where you'd find the triggers I "tried"

Keep trigger issues in the Trigeer & Scrips part please.

Wait at least a day or 2 before bumping threads or posting new stuff about the same issue (never dubble post by the way)

erm so what the problem?

Forget my opening post, what triggers should I use to make it so a player can be allied to everyone else as Human but when he's in Death form, he's basically enemies with the other Humans.
