Win This Turn! A Dino-Tastic Puzzle

Roar! Your Huatli, Poet of Unity // Roar of the Fifth People
How does this work?
Pretend you're playing a regular game of magic, but it's your turn & your opponent is tapped out with no interaction. As such you can figure out the turn & try to win in a completely solitaire fashion. Given it's a puzzle, we promise you CAN win as well, as long as you find the line.
For any decisions your opponent would make it, think through all their options and choose the one that would stop you from winning if there is one. In this puzzle, that's mostly about blocking and you can assume they'll block in order to reduce damage as much as they can, even if that means chumping.
Once you've found the solution (or if you give up), you can confirm against the official one here.
Any Hints?
