I think you're right on little Sigarda. I wasn't going to replace, but play it alongside the other Sigarda. The token production was really what caught my eye, but you helped me see that it isn't an overwhelm kind of deck. It plays hard-to-answer threats that go over the top of Deed and other creatures in the format.
Honestly, I'll probably just copy/paste your sideboard. I have everything in there. I really wanted to squeeze in Bitterblossom into the board, it seems very good in grindy matchups like Miracles.
