Entropy is not really a concept, and as such it has no place in Ars Magica.

Absolutely. This concept was defined mid 1800, and was purely linked to a physical phenomenon. No correlation to luck.

Luck on the other hand is "very real", in the sense that Fortuna or Fors Fortuna as divinity of luck and fate exists in the Roman mythology.
Now, the interesting point is that Fortuna is not pure luck, it is also fate and destiny. So it seems that if a mage could integrate Fortunam from the Learned Magician, luck could have its own Form. The way Fortunam is described in Hedge Magic looks likes it is affecting mostly random event, but can be used to grant a bonus for specific activities.

"Chaos" exists in the Greek mythology, but is describded as a shapeless mass, where the first divinity came from.
It is not matching the modern concept of entropy, except for its shapeless status. Chaos is more akin to a primordial ooze where everything originated from. Closer to the vision of Chaos as Moorcock described it in his various cycles, without its destructive urge.
However, if a mage would look at improving Creo (creation of full-fledge human life with soul and everything ?), contacting a Daimon of Chaos could be an interesting lead - and of course would open the whole discussion about Creation of human and soul being the only perview of the Divine - but it would make an interesting - if not theological - Saga.

right,the fortunam is more or less waht i had in mind. however curiously the book doesn't mention anything about integrating it. so i assumed, the implication was that the 10 forms can do it themselves?

concerning creatin/destroying ideas. i did not mean it in the strictly mental(i.e brain) sense. for instance a particular medieval silk weaving guild is an "idea" the mandate of heaven in chinese philosophy is an idea,which if attacked,can be withdrawn and can even have a domino effect of physical consequences.or increasing the idea of progressivism might help the democratic party win the next election. and so on
