>Lunala and Solgaleo were the only SM Pokemon the council determined were good enough to be sent straight to Ubers. Both of them were incredibly strong and good given what we knew about them and we believed that it would be in the best interest of the tier to start them in Ubers as opposed to OU.If you want specifics, some Pokemon can check Solageo on the short term as it struggles with status. On a larger scale, thanks to its immense bulk and varied movepool, most of what could check Solgaleo simply wouldn't survive long enough to see it through.
