I've played support yorick completely seriously with success, pseudo-cc that they can't spellshield is pretty decent, and maiden allows for pretty disgusting damage if they don't respect her.
New players necessarily have brand (it's given to them at level 4) who works. I guess they could use ashe (given at level 2) too.
If they're legit new players though, they're probably not really playing with a meta anyway, so it ends up being a matter of what pick is best suited to support ww 'adc' since thats how it goes at early levels.
