Raidho the travel rune! This one is very close to my heart, and is probably the first rune I was able to remember 
I used it as part of a bindrune (along with Elhaz/Algiz) not too long ago when I made a Safe Travels Spell Pouch and I was very happy with the results. This is a powerful rune for those on the road! 
I didn’t know Raidho was associated with these tarot cards- that makes sense! 
I know we’re probably just looking at the Major Arcana here for the runes, but I can’t help but think that for Minor Arcana Raidho could perhaps correspond with the Three of Wands too 
Thank you so much for all of your wisdom, @Susurrus- you do a really great job putting these posts together!
