Yea, I also am starting to realize wanderer is a bit too strong
Eh... sorta. It's definitely got too large a share of the 'uncomplicated way to play more of your hand/deck' advancements, and it'd feel nicer if it had an ongoing upgrade rune - maybe a stronger version of Herd Support, to incentivize keeping it in hand? (Herd Support itself needs a clearer dropdown description, incidentally; I thought it triggered when the Elk was played.)
