The city itself had opened like the petals of a flower.
Lotus. Like the petals of a lotus. Come on Wizards, you're talking about a fabled ancient city of unknown wonders here. Know your game's lexicon better and write that it opened like the petals of a lotus, not some crappy random flower.
...I know it's a really tiny and stupid thing to be annoyed about, but for some reason Wizards writing 'flower' irked me tremendously. It would have been such a simple little thing to do to make the story more "Magic".
* Even though he's only been on screen for two brief scenes, Angrath already seems like the most interesting and well-developed planeswalker they've created in a long time. Shows quite well what a difference it makes to build a character based on a story idea rather than on a boxchecking gender/ethnicity combination. More of this please.
* Huatli is an idiot. I agree fully with the commenter who said that calling a dino and then leaving without witnessing your foe's demise just smacks of a reversed Bond villain move.
* Even with the power to sense Vona moving through the jungle, I thought Tishana was a wee bit to quick in believing Jace--whom she knew to be capable of illusions--when he said he didn't have the compass. She didn't even ask him to explain himself, but instead neatly filled in all the blanks herself and merely asked him to confirm her theory. Looks like her encounter with Kumena didn't teach her much on the naivety-front.
* Regaining your memories by hitting your head? Really Wizards?
* Vraska wondering about Jace's hair was an unexpected gem. I'm not a Vraska/Jace shipper at all, but having a gorgon wonder about the softness of her interest's hair was quite cute and believable.
