AI is too conservative to play life for fetch

[Jean le Chauve]

Void reported:

Computer was to afraid to use "Verdant Catacombs" that he had three of them on the Battlefield and couldn't play any usefull spell.
I was playing with "Conserve life early" on.
The behaviour is probably similar with the rest of Zendikar fetch lands for 1 life.

It was especially visible on turn 8

void report:
Are there any functions (besides targeting positive-neutral-negative) to steer the AI behavior for particular card?

FranAvalon:
AI behabiours helpers only works with determinated abilities, and that are the options.

Any posibility to extend it? i would like force IA to cast polymorph on its controlled creatures.
