Nice guide! Thanks for your comment on my guide. I would consider an Eve of Harvest instead of the Clockwork, for some insane sustain. Her abilities have such a short cool down anyway, you don't need Clockwork. On the other hand, if you decide to max the Core Collaspe, clockwork is very helpful. Also, Broken Myth should be done slightly earlier, as it is just OP on Celeste right now. It should be done before the second Shatterglass, as by this (click link) article, Broken Myth is stronger...
