I'm planning a deck using elite Kanan Jarrus and elite General Rieekan with Fortify.

Here is the link:

Can you recommend some edits?

Maybe place a deploy squadron instead of alter. Also get non-side focused mill instead of block( meaning not just melee sides in case your opponent plays a ranged deck)
