Here's my Unhappy/Ra deck, No preferred Skill necessary but some skills could work with this one. Thanks to the image checking, it could take some time for the picture to appear.
I used Anti-Magic Arrows since I don't have Emergency Provisions for LP gain from using both traps on the last turn.
I only lost 3 times from 20 with mine. As for 2 Sanctuary, I think you meant to say 2 Solemn which I only relied on using 3 SB's and SW's just to give Magic Planter something to use for its effect of drawing cards. Also, I took arrows out for Spellbook Organization to make sure the next few cards are ones that I needed.
I run similar deck but using 3 Rai-Mei, 3 Draining Shield, & a Double Summon instead of Arrows, Planter, and Solemn. So far only lose 1 time w/ over 30 duels (including w/ Lv 30). Draw Pass
Crystal Seer can be replaced w/ Sangan or monster w/ drawing eff like Skelengel. Draining Shield can be replaced w/ Enchanted Javelin. Double Summon can be replaced w/ Arrivalrival, Photon Lead, or any cards.
Double Summon isn't necessary if you can maintain 3 monster, mainly Unhappy Girls, on the field before last turn and its very easy w/ Rai-Mei & Crystal Seer/Sangan, so yeah it can be replaced w/ any card (add any Glossy/Prisma if you want). Can run w/o skill, preferable LP Boost alpha, Draw Pass, or Restart.
