What's your opinion on allowing Yuan-Ti PCs using the Mordenkainen's Monsters of the Multiverse version? Do you think they're overpowered compared to other PC races? I felt the Volo's version was overpowered with both magic resistance & poison immunity; the newer version has poison resistance (similar to dwarves but with what seems a more limited saving throw advantage) and spell resistance. I'm less sure if the new version is obviously overpowered, but advantage on saves vs spells certainly feels like a big deal.
