Landfall decks generally need to play fast and hit hard early. If you atre making it to the late game, you are probably way behind.
With that in mind, your
jaddi offshoot (defensive creatures in general) ate not going to be great to play. You'd be better replacing that with the red one drop with landfall. (Can't remember the name right now.) I also wouldn't play
nissa's renewal or
nissa's revelation because you can't play them till late in the game. There are a couple of creatures that allow you to search for a land when they come into play and I think you'd get more value from them.
If you are willing to spend a little bit for it, I would replace some of your
plains and forests with some additional cinder glades and buy a few of the khan's fetchlands. They help with mana fixing like the
evolving wilds, however they allow you to search for the cinder glades and they don't come in to play tapped. (Assuming you have two basic lands in play, otherwise you can hunt up a basic land. ) This means you can still get the double trigger, but can use the mana on the same turn.
I like the start you have here.
