Hey, I attempted a profile write up if you're interested:
Upon Mega Evolving, Cherrim has discovered a means to create its own light with fire, and can at last enjoy being cheerful and energetic even in the darkest of nights or cloudiest of days. Although being in bright sunlight increases its vitality even more, it runs the risk of wearing itself out too quickly.
this is the perfect pokemon for a grass and fire type so this is needed and right now...
Also, I feel like Solar Ray should have power of 100 or slightly higher, but the catch is that it ONLY works during the Sunny weather condition. It should have a 20% chance to lower opponent's accuracy as well as a 25% chance to burn the opponent. However, for the sun to even become active, I feel it's ability should be changed to a renamed version of the Drought ability (because Drought doesn't really fit as an ability for such an amazing flower).
