Overall, Alela is a great commander for vehicles and artifacts in general, and her value-centric game plan here makes her a stealth threat until its much too late
Foundations is a way for Wizards to put in mechanically unique cards as it doesnt have any set wide mechanics that we are used to with normal sets
Being able to ramp the best land out of the top four cards of your deck at instant speed is already very useful, but the fact that you can still draw one of them into your hand as a fall back means that you wont have a major downside (see Growth Spiral for a similar effect)
I really like this design since its an effect that lasts throughout each players turn, and you get to change your target from turn to turn if you need to
There was a thread here on E4 about it somewhere I think
