Well, this seems like the sort of thing I should respond to.
So! A few things to keep in mind with Ms. Hartley! The first is this: Lands and Exile. Those are her things, for the most part, so sticking with that theme is a good idea. You've already got a solid handle on that, so fair game so far.
Path to Exile,
Cloudshift, and
Explore are all some of the best cards to represent Aloise's abilities.
Creature, preferably, should be benign or beneficial towards your game plan, rather than harmful to your opponents.
Stonecloaker is an excellent addition to any deck themed around Aloise, and I like the idea of Allies featuring prominently in the deck - except that she had never personally visited Zendikar, so I'm not sure how much sense that makes.
A diversity of creature types shows her ability to make friends. Loxodons, Rhox, Humans, Elves, Merfolk, Leonin, Kithkin, Treefolk, and so on. Anything that gains life, gives protection, or otherwise keeps your stuff safe is certainly a good addition.
Loxodon Hierarch and
Rhox Faithmender come to mind.
As for finally winning the game, getting their via evasion and teamwork between creatures should do the trick. Aloise would be more interested in keeping her friends safe than participating directly in the nitty-gritty of the fight.
Test of Endurance,
Felidar Sovereign, and
Epic Struggle are interesting alternate win conditions.
Evangelize also strikes me as a pretty interesting choice.
Hope this helps!
