Foundations introduces only 12 new commanders into the format. What are your thoughts regarding them?

The Foundations main set introduces 12 new legends to EDH. In terms of new legendary creatures, this is quite a low number. What are your thoughts on the new commanders?

• Who do you plan on building?
• Which do you think will be popular?
• Overall, what excites you the most about the set?

Foundations contains a total of 41 legendary creatures, with the other 29 being reprints. The 12 new legends can be viewed here.
