general tip on getting ai to use an ability on a card.
titan forge for exsample
[card]
name=Titan Forge
auto={3}{T}:counter(0/0,1,Charge)
auto={T}{C(0/0,-3,Charge)}:token(Golem,Artifact Creature Golem,9/9)
text={3},{T}: Put a charge counter on Titan Forge. -- {T}, Remove three charge counters from Titan Forge: Put a 9/9 colorless Golem artifact creature token onto the
battlefield.
mana={3}
type=Artifact
[/card]
with the counter ability above the counter cost ability, ai will rarely ever use the titan forge to make a token.
however if you change the order around, ai will see the token ability first...then if it can afford it then it will make a token.
