[Regarding V13 (Major Update!)]

You KNOW that even with some planned content cut, the amount of new content in V13 is going to be incredible. I'm so excited to play it, and if you release more in 13.5 I'm going to be excited AGAIN

[Crest Suggestions! (CLOSED)]

Gigalith Crest: gives a Solar Power buff (increased SPA in sun), but maybe more powerful and certainly without hp cost (and maybe activate it in some fields as well)
Reasoning: the Pokedex says Gigalith can fire powerful energy blasts when the sun is out, and it can learn such moves (like Solar Beam), but its SPA is too low to use them

Edit: or just swap attack and special attack, that can work too
