ET- Holder may play the next Enhancement
Cherubim- May band to a Purple Brigade Hero
Amalekite Slave- If blocking, may place in opponents land of bondage to search deck for a human evil character and add it to battle.
Peace Treaty- OT hero ignores one evil brigade except orange or may band to human hero.

ET+Cherubim make RA. ET plays PT and ignores Gray. ET is discarded by Christian Martyr. Is the ignore still active without a purple brigade hero in battle.

If it is? If AS is played can a gray brigade EC be brought into battle?

I agree because christian martyr doesn't interrupt the battle so it doesn't make the enhancement get wasted.  Since Cherubim is the only logical target for the SA if you select him I see no reason why the ability would not stick.

Peace Treaty specifies OT hero (singular).  You pick the OT hero to get the ignore ability for that phase.  Since you picked Cherubim (the only OT hero in battle), then it continues to ignore.  If ET were OT and you had picked him, then there would be no restriction on who could block.
