New player to MTG - tried adapting a deck and could do with some guidance. Planeswalker / landfall

[idle wren]

Started playing around a month ago, with some background in other TCG's I know my strong point for decks is adapting rather than creating.

The aim was a planeswalker / landsfall deck with Nissa as a focus (the original deck is very similar and can be found on archidekt under ecology study group). I've played the deck twice now with some cards missing but felt a bit like I needed more of a finish if I couldn't draw into Tatyova. Added some considerations to the maybeboard in that regard but any feedback would be welcome!

[[avenger of zedikar]] is a pretty good finisher too
